"The version of aioHTTP installed on the remote host is prior to 3.12.14. It is, therefore, affected by a
request smuggling vulnerability:

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python
    parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If
    a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is
    enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy
    protections. Version 3.12.14 contains a patch for this issue. (CVE-2025-53643)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
