CVE-2026-111065 – AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, Max-Age processing can overflow and skip closing a connection. An attacker can consequently exhaust the connection pool temporarily until garbage collection resolves the connections. This issue is fixed in version 3.14.4.
