SCA: security update for aiohttp (GHSA-hg6j-4rv6-33pg)

high Tenable Self-Hosted Container Security Plugin ID 442598

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 3.14.0,
 cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect. If
 a developer uses the `cookies` parameter on a per-request basis then sensitive data might be leaked to an
 attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade,
 using a `Cookie` header in the `headers` parameter is not vulnerable. (CVE-2026-47265)

Solution

Update the aiohttp library and its related packages to version 3.14.0 or later.
