SCA: security update for aiohttp (GHSA-cq5v-8q36-5273)

high Tenable Cloud Security Plugin ID 445607

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 3.14.3, an out-
 of-bounds heap read could occur in the C response parser while building an error message for a malformed
 response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the
 client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp
 error-position pointer was used to build a snippet for malformed chunked responses and malformed request
 or response bytes at the buffer end. This issue is fixed in version 3.14.3. (CVE-2026-69244)

Solution

Update the aiohttp library and its related packages to version 3.14.3 or later.
