The remote Fedora 37 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-0806784f24 advisory.
Cookie
HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.Cookie
header and unknowingly leak information via HTTP redirects to a different origin if that user doesn’t disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header
special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.
However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP
redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been
patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)
