Cross-site scripting in affected Fortinet FortiADC releases allows remote authenticated users to execute script via crafted HTTP requests. Fortinet has not identified the affected GUI endpoint or the request field whose value is emitted without context-appropriate encoding. Exploitation requires high-privilege access and user interaction and can read or alter data in the victim's browser context without interrupting the appliance.
