python-aiohttp: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python
CVE-2026-69243 is fixed in 3 products on 1 platform, first by DEBIAN-CVE-2026-69243, released August 3, 2026. It is not reported as exploited. Patch Radar priority: High.
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the HTTP parsers were vulnerable to a request smuggling attack relating to WebSocket upgrades. If using the server-side component, an attacker may be able to execute a request smuggling vulnerability using an edge case in the WebSocket upgrade procedure. A WebSocket upgrade request with a body could cause the parser to switch protocols before the complete request body was received, leaving trailing bytes to be handled as upgraded-protocol or pipelined data rather than normal HTTP body data. This issue is fixed in version 3.14.2.
