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

  - Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, List#set,
    List#setSize, List#setIn, List#updateIn, and the functional set, setIn, and updateIn mishandle an index or
    size in the range 2 ** 30 to 2 ** 31 in setListBounds in src/List.js, causing an empty List to enter an
    uncatchable infinite loop, a populated List to allocate without bound until process abort, or setSize to
    silently wrap large values. This issue is fixed in versions 4.3.9 and 5.1.8. (CVE-2026-59879)

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.

  - Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, List#set,     List#setSize, List#setIn, List#updateIn, and the functional set, setIn, and updateIn mishandle an index or     size in the range 2 ** 30 to 2 ** 31 in setListBounds in src/List.js, causing an empty List to enter an     uncatchable infinite loop, a populated List to allocate without bound until process abort, or setSize to     silently wrap large values. This issue is fixed in versions 4.3.9 and 5.1.8. (CVE-2026-59879)

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