CVE-2026-54273 PUBLISHED CVSS 6.6 MEDIUM

Reported by GitHub_M · Published June 22, 2026

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.
