Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.

  - In Eclipse Jetty, across various versions of `jetty-server`, and `jetty-proxy`, the host     whitelist/blacklist is case-sensitive, and would allow hosts through that only differ by case.
    (CVE-2026-18660)

Note that Nessus relies on the presence of the package as reported by the vendor.
