CVE-2026-34993 AIOHTTP Vulnerable to Deserialization of Untrusted Data

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 man...

CVE-2026-34993

In CVE-2026-34993, AIOHTTP prior to 3.14.0 is vulnerable: using CookieJar.load() with untrusted input may lead to arbitrary code execution. The issue stems from deserializing untrusted data in the cookie jar. The advisory notes that most applications will be unaffected since data are user-owned, ...
