The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 24aad1ab-d452-11f1-bae2-3497f65b111b advisory.

    Oracle reports:
    The October 2026 Critical Patch Update contains 98 new security                 patches for Oracle MySQL, 29 of which may be remotely                 exploitable without authentication.
    Eight of them affect the MySQL Connectors. The most severe, in                 Connector/J, can be exploited over a network without                 authentication. The fixes are contained in release 26.10.0 of                 each connector.

Tenable has extracted the preceding description block directly from the FreeBSD 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.
