Affected: aio-libs aiohttp, Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9, Red Hat Ansible Automation Platform 2.6 for RHEL 9, Red Hat Satellite 6.16 for RHEL 8, Red Hat Satellite 6.16 for RHEL 9, Red Hat Satellite 6.17 for RHEL 9, Red Hat Satellite 6.18 for RHEL 9, Red Hat Satellite 6.19 for RHEL 9, Red Hat AI Inference Server 3.3 and 20 more

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.

Affected: PyPI: aiohttp

### 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.
