CVE-2026-54273
CVE-2026-54273 · AIOHTTP: HTTP/1 Pipelined Requests Queue Without Limit
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. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This vulnerability is fixed in 3.14.1.
