"According to the versions of the python-urllib3 package installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

    urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed
    from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still
    forward these sensitive headers. This vulnerability is fixed in 2.7.0.(CVE-2026-44431)

Tenable has extracted the preceding description block directly from the EulerOS python-urllib3 security advisory.

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