"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - Concurrent execution using shared resource with improper synchronization ('race condition') vulnerability
    in Apache Struts. Where a localized message formats a date or time argument, the formatter retained for
    that message by the application-wide text provider is used by concurrently served requests without
    isolation, so a value belonging to one user can appear in another user's response, or the rendering can
    fail and surface as a server error. Applications whose localized messages format no date or time arguments
    are not affected. This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33,
    from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or
    7.4.0, which fixes the issue. (CVE-2026-104714)

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