SCA: security update for aiohttp (GHSA-mfx4-hv73-q22v)

medium Tenable Self-Hosted Container Security Plugin ID 445594

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-69243)

Solution

Update the aiohttp library and its related packages to version 3.14.2 or later.
