Affected versions of Black are vulnerable to Regular Expression Denial of Service (ReDoS) via the lines_with_leading_tabs_expanded function in the strings.py file. An attacker could exploit this vulnerability by crafting a malicious input that causes a denial of service.

Affected versions of the black package are vulnerable to Path Traversal due to unsanitized user input in a cache file name. The vulnerability exists because Black incorporates the --python-cell-magics option value into the cache filename without sanitizing path elements, allowing the computed cache path to escape the intended cache directory.
