Insecure deserialization In python-aiohttp

Description

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

Mitigation

Update Impact
