Summary

python-aiohttp security update

Details

Async http client/server framework (asyncio).

Security Fix(es):

Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications.(CVE-2026-34993)

If a developer uses the cookies parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect.(CVE-2026-47265)
