There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input
    carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is
    returned with its host verbatim and no error set. As a result fast-uri's own entry points disagree with
    each other: parse, resolve, normalize, and equal can yield different hosts for the same input depending
    only on whether a scheme is written out, and equal can return opposite verdicts for the same pair of
    hosts. An application that extracts a host with fast-uri to check it against a policy list and then
    resolves the same reference can make its decision on one host while the destination is another, enabling
    host confusion and policy bypass. The affected versions are 2.4.2 up to but not including 2.4.5, 3.1.3 up
    to but not including 3.1.6, and 4.0.1 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6,
    and 4.1.3, which canonicalize the host consistently across the resolve path. Users should upgrade to a
    patched version. (CVE-2026-75931)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:74503 advisory.

    Red Hat Satellite is a system management solution that allows organizations     to configure and maintain their systems without the necessity to provide     public Internet access to their servers or other client systems. It     performs provisioning and configuration management of predefined standard     operating environments.

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.

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