Echo: aiohttp: security update to 3.12.14python-aiohttp: security update to 3.13.1-1

medium Tenable Cloud Security Plugin ID 459862

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 version 3.12.14,
 the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections
 of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions)
 or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to
 bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.
 (CVE-2025-53643)

Solution

Update the aiohttp library and its related packages to version 3.12.14 or later.
