Twine 2.0.0 updates requests to 2.20 (or later) to include a security fix.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Affected versions of Requests are vulnerable to proxy credential leakage. When redirected to an HTTPS endpoint, the Proxy-Authorization header is forwarded to the destination server due to the use of rebuild_proxies to reattach the header. This may allow a malicious actor to exfiltrate sensitive information.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the jupyterlab package are vulnerable to Improper Neutralisation of Input During Web Page Generation due to the HTML sanitiser allowlisting the data-commandlinker-command and data-commandlinker-args attributes on button elements while the CommandLinker handler executes the named command without verifying the origin of the click target. The CommandLinker registers a global click listener on document.body that dispatches whichever command is named in the data-commandlinker-command attribute of the clicked element, so a notebook or Markdown file containing a pre-saved HTML cell output with a deceptive button rendered in the output area is sufficient to invoke arbitrary JupyterLab commands without any code being submitted to a kernel. An attacker who shares a notebook or Markdown file via email, GitHub, or a Binder link can, on a single victim click, execute arbitrary code in available kernels, delete files, or spawn multiple kernels and terminals to exhaust server resources, and through a multi-click sequence that grants clipboard access on Chromium-based browsers can obtain full terminal access in the user environment.

CVE-2024-22421 is a vulnerability in Jupyter Notebook where clicking a malicious link could expose Authorization and XSRFToken tokens to third parties in older jupyter-server versions. Patched versions include JupyterLab 4.1.0b2, 4.0.11, and 3.6.7. Users are advised to upgrade jupyter-server to version 2.7.2 or newer, which includes a fix for a redirect vulnerability. No other workaround has been identified.

Affected versions of the jupyterlab package are vulnerable to Reverse Tabnabbing due to LaTeX typesetter–generated links not enforcing the noopener attribute. Links produced by LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook omit rel=noopener, and if a (third-party) typesetter also adds target=_blank, the newly opened page can access window.opener.

Jupyterlab 3.1.0 upgrades the 'marked' dependency to fix a vulnerability.

JupyterLab is vulnerable to HTML injection, leading to DOM Clobbering, which allows attackers to access sensitive data and perform arbitrary actions as the compromised user. This vulnerability occurs when a user opens a malicious notebook with Markdown cells or a Markdown file in JupyterLab.

Jupyterlab 3.1.0b2 upgrades the 'marked' underlying dependency from '@jupyterlab/rendermime' with a known security vulnerability.

Jupyterlab versions 3.1.4, 3.0.17, 2.3.2, 2.2.10 and 1.2.21 include a fix for CVE-2021-32797: In affected versions, an untrusted notebook can execute code on load. In particular, jupyterlab doesn’t sanitize the action attribute of html "<form>". Using this it is possible to trigger the form validation outside of the form itself. This is a remote code execution, but requires user action to open a notebook.

Affected versions of the pip package are vulnerable to Path Traversal due to an incorrect directory containment check when extracting wheel archives. In src/pip/_internal/utils/unpacking.py, the is_within_directory() helper used os.path.commonprefix() (character-by-character) to compare directory and target paths, allowing crafted paths like a parent-directory substring match to be treated as safely inside the installation directory.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

Affected versions of the pip package are vulnerable to Arbitrary File Overwrite due to improper validation of symbolic link targets in the fallback tar extraction code. In src/pip/_internal/utils/unpacking.py, the _untar_without_filter routine used when the Python tarfile module lacks PEP 706 (no tarfile.data_filter) extracted symlink members with tar._extract_member without verifying that link destinations resolve under the extraction root, a check later added via the is_symlink_target_in_tar helper.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Affected versions of Requests are vulnerable to proxy credential leakage. When redirected to an HTTPS endpoint, the Proxy-Authorization header is forwarded to the destination server due to the use of rebuild_proxies to reattach the header. This may allow a malicious actor to exfiltrate sensitive information.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the jupyterlab package are vulnerable to Improper Neutralisation of Input During Web Page Generation due to the HTML sanitiser allowlisting the data-commandlinker-command and data-commandlinker-args attributes on button elements while the CommandLinker handler executes the named command without verifying the origin of the click target. The CommandLinker registers a global click listener on document.body that dispatches whichever command is named in the data-commandlinker-command attribute of the clicked element, so a notebook or Markdown file containing a pre-saved HTML cell output with a deceptive button rendered in the output area is sufficient to invoke arbitrary JupyterLab commands without any code being submitted to a kernel. An attacker who shares a notebook or Markdown file via email, GitHub, or a Binder link can, on a single victim click, execute arbitrary code in available kernels, delete files, or spawn multiple kernels and terminals to exhaust server resources, and through a multi-click sequence that grants clipboard access on Chromium-based browsers can obtain full terminal access in the user environment.

CVE-2024-22421 is a vulnerability in Jupyter Notebook where clicking a malicious link could expose Authorization and XSRFToken tokens to third parties in older jupyter-server versions. Patched versions include JupyterLab 4.1.0b2, 4.0.11, and 3.6.7. Users are advised to upgrade jupyter-server to version 2.7.2 or newer, which includes a fix for a redirect vulnerability. No other workaround has been identified.

Affected versions of the jupyterlab package are vulnerable to Reverse Tabnabbing due to LaTeX typesetter–generated links not enforcing the noopener attribute. Links produced by LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook omit rel=noopener, and if a (third-party) typesetter also adds target=_blank, the newly opened page can access window.opener.

Jupyterlab 3.1.0 upgrades the 'marked' dependency to fix a vulnerability.

JupyterLab is vulnerable to HTML injection, leading to DOM Clobbering, which allows attackers to access sensitive data and perform arbitrary actions as the compromised user. This vulnerability occurs when a user opens a malicious notebook with Markdown cells or a Markdown file in JupyterLab.

Jupyterlab 3.1.0b2 upgrades the 'marked' underlying dependency from '@jupyterlab/rendermime' with a known security vulnerability.

Jupyterlab versions 3.1.4, 3.0.17, 2.3.2, 2.2.10 and 1.2.21 include a fix for CVE-2021-32797: In affected versions, an untrusted notebook can execute code on load. In particular, jupyterlab doesn’t sanitize the action attribute of html "<form>". Using this it is possible to trigger the form validation outside of the form itself. This is a remote code execution, but requires user action to open a notebook.

Jupyterlab 3.0.8 updates its dependency 'marked' to v2.0.0 to address a vulnerability. See also <https://github.com/jupyterlab/jupyterlab/pull/9809>.

Pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.
It is recommended that you:
- Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.
- Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.
- Select a tool to bootstrap and then run tests such as tox.

Affected versions of the pip package are vulnerable to Path Traversal due to an incorrect directory containment check when extracting wheel archives. In src/pip/_internal/utils/unpacking.py, the is_within_directory() helper used os.path.commonprefix() (character-by-character) to compare directory and target paths, allowing crafted paths like a parent-directory substring match to be treated as safely inside the installation directory.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

Affected versions of the pip package are vulnerable to Arbitrary File Overwrite due to improper validation of symbolic link targets in the fallback tar extraction code. In src/pip/_internal/utils/unpacking.py, the _untar_without_filter routine used when the Python tarfile module lacks PEP 706 (no tarfile.data_filter) extracted symlink members with tar._extract_member without verifying that link destinations resolve under the extraction root, a check later added via the is_symlink_target_in_tar helper.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

Wheel 0.38.1 includes a fix for CVE-2022-40898: An issue discovered in Python Packaging Authority (PyPA) Wheel 0.37.1 and earlier allows remote attackers to cause a denial of service via attacker controlled input to wheel cli.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Affected versions of Requests are vulnerable to proxy credential leakage. When redirected to an HTTPS endpoint, the Proxy-Authorization header is forwarded to the destination server due to the use of rebuild_proxies to reattach the header. This may allow a malicious actor to exfiltrate sensitive information.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the jupyterlab package are vulnerable to Improper Neutralisation of Input During Web Page Generation due to the HTML sanitiser allowlisting the data-commandlinker-command and data-commandlinker-args attributes on button elements while the CommandLinker handler executes the named command without verifying the origin of the click target. The CommandLinker registers a global click listener on document.body that dispatches whichever command is named in the data-commandlinker-command attribute of the clicked element, so a notebook or Markdown file containing a pre-saved HTML cell output with a deceptive button rendered in the output area is sufficient to invoke arbitrary JupyterLab commands without any code being submitted to a kernel. An attacker who shares a notebook or Markdown file via email, GitHub, or a Binder link can, on a single victim click, execute arbitrary code in available kernels, delete files, or spawn multiple kernels and terminals to exhaust server resources, and through a multi-click sequence that grants clipboard access on Chromium-based browsers can obtain full terminal access in the user environment.

CVE-2024-22421 is a vulnerability in Jupyter Notebook where clicking a malicious link could expose Authorization and XSRFToken tokens to third parties in older jupyter-server versions. Patched versions include JupyterLab 4.1.0b2, 4.0.11, and 3.6.7. Users are advised to upgrade jupyter-server to version 2.7.2 or newer, which includes a fix for a redirect vulnerability. No other workaround has been identified.

Affected versions of the jupyterlab package are vulnerable to Reverse Tabnabbing due to LaTeX typesetter–generated links not enforcing the noopener attribute. Links produced by LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook omit rel=noopener, and if a (third-party) typesetter also adds target=_blank, the newly opened page can access window.opener.

Jupyterlab 3.1.0 upgrades the 'marked' dependency to fix a vulnerability.

JupyterLab is vulnerable to HTML injection, leading to DOM Clobbering, which allows attackers to access sensitive data and perform arbitrary actions as the compromised user. This vulnerability occurs when a user opens a malicious notebook with Markdown cells or a Markdown file in JupyterLab.

Jupyterlab 3.1.0b2 upgrades the 'marked' underlying dependency from '@jupyterlab/rendermime' with a known security vulnerability.

Jupyterlab versions 3.1.4, 3.0.17, 2.3.2, 2.2.10 and 1.2.21 include a fix for CVE-2021-32797: In affected versions, an untrusted notebook can execute code on load. In particular, jupyterlab doesn’t sanitize the action attribute of html "<form>". Using this it is possible to trigger the form validation outside of the form itself. This is a remote code execution, but requires user action to open a notebook.

Jupyterlab 3.0.8 updates its dependency 'marked' to v2.0.0 to address a vulnerability. See also <https://github.com/jupyterlab/jupyterlab/pull/9809>.

Pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.
It is recommended that you:
- Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.
- Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.
- Select a tool to bootstrap and then run tests such as tox.

Affected versions of the pip package are vulnerable to Path Traversal due to an incorrect directory containment check when extracting wheel archives. In src/pip/_internal/utils/unpacking.py, the is_within_directory() helper used os.path.commonprefix() (character-by-character) to compare directory and target paths, allowing crafted paths like a parent-directory substring match to be treated as safely inside the installation directory.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

Affected versions of the pip package are vulnerable to Arbitrary File Overwrite due to improper validation of symbolic link targets in the fallback tar extraction code. In src/pip/_internal/utils/unpacking.py, the _untar_without_filter routine used when the Python tarfile module lacks PEP 706 (no tarfile.data_filter) extracted symlink members with tar._extract_member without verifying that link destinations resolve under the extraction root, a check later added via the is_symlink_target_in_tar helper.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

Wheel 0.38.1 includes a fix for CVE-2022-40898: An issue discovered in Python Packaging Authority (PyPA) Wheel 0.37.1 and earlier allows remote attackers to cause a denial of service via attacker controlled input to wheel cli.

Pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.
It is recommended that you:
- Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.
- Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.
- Select a tool to bootstrap and then run tests such as tox.

Affected versions of the pip package are vulnerable to Path Traversal due to an incorrect directory containment check when extracting wheel archives. In src/pip/_internal/utils/unpacking.py, the is_within_directory() helper used os.path.commonprefix() (character-by-character) to compare directory and target paths, allowing crafted paths like a parent-directory substring match to be treated as safely inside the installation directory.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

Affected versions of the pip package are vulnerable to Arbitrary File Overwrite due to improper validation of symbolic link targets in the fallback tar extraction code. In src/pip/_internal/utils/unpacking.py, the _untar_without_filter routine used when the Python tarfile module lacks PEP 706 (no tarfile.data_filter) extracted symlink members with tar._extract_member without verifying that link destinations resolve under the extraction root, a check later added via the is_symlink_target_in_tar helper.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

Wheel 0.38.1 includes a fix for CVE-2022-40898: An issue discovered in Python Packaging Authority (PyPA) Wheel 0.37.1 and earlier allows remote attackers to cause a denial of service via attacker controlled input to wheel cli.

Twine 2.0.0 updates requests to 2.20 (or later) to include a security fix.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Affected versions of Requests are vulnerable to proxy credential leakage. When redirected to an HTTPS endpoint, the Proxy-Authorization header is forwarded to the destination server due to the use of rebuild_proxies to reattach the header. This may allow a malicious actor to exfiltrate sensitive information.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the jupyterlab package are vulnerable to Improper Neutralisation of Input During Web Page Generation due to the HTML sanitiser allowlisting the data-commandlinker-command and data-commandlinker-args attributes on button elements while the CommandLinker handler executes the named command without verifying the origin of the click target. The CommandLinker registers a global click listener on document.body that dispatches whichever command is named in the data-commandlinker-command attribute of the clicked element, so a notebook or Markdown file containing a pre-saved HTML cell output with a deceptive button rendered in the output area is sufficient to invoke arbitrary JupyterLab commands without any code being submitted to a kernel. An attacker who shares a notebook or Markdown file via email, GitHub, or a Binder link can, on a single victim click, execute arbitrary code in available kernels, delete files, or spawn multiple kernels and terminals to exhaust server resources, and through a multi-click sequence that grants clipboard access on Chromium-based browsers can obtain full terminal access in the user environment.

CVE-2024-22421 is a vulnerability in Jupyter Notebook where clicking a malicious link could expose Authorization and XSRFToken tokens to third parties in older jupyter-server versions. Patched versions include JupyterLab 4.1.0b2, 4.0.11, and 3.6.7. Users are advised to upgrade jupyter-server to version 2.7.2 or newer, which includes a fix for a redirect vulnerability. No other workaround has been identified.

Affected versions of the jupyterlab package are vulnerable to Reverse Tabnabbing due to LaTeX typesetter–generated links not enforcing the noopener attribute. Links produced by LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook omit rel=noopener, and if a (third-party) typesetter also adds target=_blank, the newly opened page can access window.opener.

Jupyterlab 3.1.0 upgrades the 'marked' dependency to fix a vulnerability.

JupyterLab is vulnerable to HTML injection, leading to DOM Clobbering, which allows attackers to access sensitive data and perform arbitrary actions as the compromised user. This vulnerability occurs when a user opens a malicious notebook with Markdown cells or a Markdown file in JupyterLab.

Jupyterlab 3.1.0b2 upgrades the 'marked' underlying dependency from '@jupyterlab/rendermime' with a known security vulnerability.

Jupyterlab versions 3.1.4, 3.0.17, 2.3.2, 2.2.10 and 1.2.21 include a fix for CVE-2021-32797: In affected versions, an untrusted notebook can execute code on load. In particular, jupyterlab doesn’t sanitize the action attribute of html "<form>". Using this it is possible to trigger the form validation outside of the form itself. This is a remote code execution, but requires user action to open a notebook.
