CVE-2025-53643

Summary

The Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request.

Impact

If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections.


Patch: aio-libs/aiohttp@e8d774f


Release Notes

aio-libs/aiohttp (aiohttp)

v3.12.14
