The information on this page was manually curated by our Cybersecurity Intelligence Team.
The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows
exceptions during validation that aren't handled consistently with other malformed inputs.
Latest version: 3.9.5
Async http client/server framework (asyncio)
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Security-sensitive parts of the Python HTTP parser retained minor differences in allowable character sets, that must trigger error handling to robustly match frame boundaries of proxies in order to protect against injection of additional requests. Additionally, validation could trigger exceptions that were not handled consistently with processing of other malformed input. Being more lenient than internet standards require could, depending on deployment environment, assist in request smuggling. The unhandled exception could cause excessive resource consumption on the application server and/or its logging facilities. This vulnerability exists due to an incomplete fix for CVE-2023-47627. Version 3.9.2 fixes this vulnerability. See CVE-2024-23829.
