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 3.14.2, the

    extension was not negotiated, allowing a malicious server to cause unexpected CPU and memory consumption.
    This issue is fixed in version 3.14.2. (CVE-2026-59881)

The remote Fedora 46 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-84f7af8f97 advisory.
