Authenticated script execution via unneutralized GUI input
Published Mar 11, 2025 · Updated Feb 26, 2026
XSS in the Fortinet FortiADC GUI 5.3.0 through 7.1.3, 7.2.0 through 7.2.1, and 7.4.0 lets remote authenticated users run script. FortiView and Security Logs pages render attacker-controlled request data without neutralizing it for HTML output; Fortinet has not identified the affected parameter or handler. An authenticated account and a victim who opens the affected GUI page are required, enabling script execution in that victim's browser context.
