AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. From 2.0.0 until 3.14.4, multipart request processing can retain an unbounded number of open file descriptors. An unauthenticated attacker can consequently exhaust file descriptors with specially crafted multipart requests when a handler uses Request.post(). This issue is fixed in version 3.14.4.

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. From 2.0.0 until 3.14.4,
    multipart request processing can retain an unbounded number of open file descriptors. An unauthenticated
    attacker can consequently exhaust file descriptors with specially crafted multipart requests when a
    handler uses Request.post(). This issue is fixed in version 3.14.4. (CVE-2026-111066)

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-604898 advisory.

    [2.187.0-1.0.5]
    - Fix multiple CVEs in pyjwt, aiohttp, pyOpenSSL, multidict

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. From 2.0.0 until 3.14.4,     multipart request processing can retain an unbounded number of open file descriptors.
