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

medium Tenable Self-Hosted Container Security Plugin ID 477705

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, the pure
 Python parser accepts ambiguous HTTP request framing. An unauthenticated attacker can consequently smuggle
 requests when an application uses AIOHTTP_NO_EXTENSIONS or otherwise runs without a standard wheel and an
 intermediary interprets the framing differently. This issue is fixed in version 3.14.4. (CVE-2026-111750)

Solution

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