"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-130100 advisory.

    Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is configured to use a custom Jakarta
    Authentication (formerly JASPIC)ServerAuthContext component which may throw an exception during the
    authentication process without explicitly setting an HTTP status to indicate failure, the authentication
    may not fail, allowing the user to bypass the authentication process. There are no known
    JakartaAuthentication components that behave in this way.

    This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M26, from 10.1.0-M1 through 10.1.30, from
    9.0.0-M1 through 9.0.95.

    The following versions were EOL at the time the CVE was created but are
    known to be affected: 8.5.0 though 8.5.100.Other EOL versions may also be affected.


    Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fix the issue.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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