CVE-2026-111066
CVE-2026-111066 · AIOHTTP: File descriptor exhaustion in multipart requests
This page contains facts from public vulnerability sources. Check the original advisory before updating.
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. From 2.0.0 until 3.14.4, multipart request processing can retain an unbounded number of open file descriptors. An unauthenticated attacker can consequently exhaust file descriptors with specially crafted multipart requests when a handler uses Request.post(). This issue is fixed in version 3.14.4.
