SCA: security update for aiohttp (GHSA-63hw-fmq6-xxg2)

high Tenable Self-Hosted Container Security Plugin ID 443261

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 3.14.1, it is
possible to bypass the max_line_size check in parts of an HTTP request in the C parser. If using the
optimised C parser (the default in pre-built wheels), then an attacker may be able to send oversized lines
through the HTTP parser and use an excessive amount of memory, potentially leading to DoS. This
vulnerability is fixed in 3.14.1. (CVE-2026-54277)

Solution

Update the aiohttp library and its related packages to version 3.14.1 or later.
