Affected: aio-libs aiohttp, Red Hat Ansible Automation Platform 2.4 for RHEL 8, Red Hat Ansible Automation Platform 2.4 for RHEL 9, 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 AI Inference Server 3.2, Red Hat Ansible Automation Platform 2.4, Red Hat Ansible Automation Platform 2.5, Red Hat Ansible Automation Platform 2.6 and 11 more

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a zip bomb to be used to execute a DoS against the AIOHTTP server. An attacker may be able to send a compressed request that when decompressed by AIOHTTP could exhaust the host's memory. This issue is fixed in version 3.13.3.
