CVE-2022-39950Network attack vector

Stored XSS via crafted CKEditor protected comments

Published Nov 2, 2022 · Updated Oct 25, 2024

Stored XSS in Fortinet FortiManager and FortiAnalyzer report templates allows remote authenticated users to run script in a viewer's browser. The report-template editor processes a crafted CKEditor cke_protected comment without neutralizing executable script before rendering it. A low-privilege account can store the payload, but another user must view the affected report content; the script then acts within that viewer's web session.
