"The version of python3 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2025-50181 advisory.

  - urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable
    redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable
    redirects. By default, requests and botocore users are not affected. An application attempting to mitigate
    SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain
    vulnerable. This issue has been patched in version 2.5.0. (CVE-2025-50181)

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