SCA: security update for aiohttp (GHSA-f9xw-jh8m-3mwq)

medium Tenable Self-Hosted Container Security Plugin ID 476388

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 3.14.4, an
 attacker can send an absolute-form request that causes Request.scheme to use attacker-controlled request-
 target scheme data instead of the connection protocol. Applications that use Request.scheme for security
 decisions can consequently be tricked into treating an unencrypted connection as encrypted or an encrypted
 connection as unencrypted. This issue is fixed in version 3.14.4. (CVE-2026-111748)

Solution

Update the aiohttp library and its related packages to version 3.14.4 or later.
