Vulnerability description
DayBreach CVE AI Research
CVE-2026-34993 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
