Echo: python-aiohttp: security update to 3.14.3-1+e2

high Tenable Self-Hosted Container Security Plugin ID 477702

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. From 2.0.0 until 3.14.4,
 multipart request processing can retain an unbounded number of open file descriptors. An unauthenticated
 attacker can consequently exhaust file descriptors with specially crafted multipart requests when a
 handler uses Request.post(). This issue is fixed in version 3.14.4. (CVE-2026-111066)

Solution

Update the python-aiohttp library and its related packages to version 3.14.3-1+e2 or later.
