NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-aiohttp-auto package and not the py3-aiohttp-auto package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the WebSocket client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated, allowing a malicious server to cause unexpected CPU and memory consumption. This issue is fixed in version 3.14.2.
