Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of FortiManager installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-26-171 advisory.

(CVE-2026-22575)

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