AIOHTTP is Vulnerable to Deserialization of Untrusted Data ### Summary Using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. ### Impact Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. ### Workaround If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitise the files before loading. ----- Patch: https://github.com/aio-libs/aiohttp/commit/dcf40f30637e8752c76781cf6703b5a236749a00

gitlab/pypi/aiohttp/CVE-2026-34993

AIOHTTP is Vulnerable to Deserialization of Untrusted Data Using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution.

pypa/aiohttp/PYSEC-2026-2104

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. Version 3.14.0 patches the issue. If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitize the files before loading.
