python-aiohttp: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python
CVE-2025-69229 is fixed in 5 products on 1 platform, first by python3-aiohttp 3.0.1-1ubuntu0.1~esm6, released January 5, 2026. It is not reported as exploited. Patch Radar priority: Routine.
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. If an application makes use of the request.read() method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time. This issue is fixed in version 3.13.3.
