Subscriber-level stored XSS via featured video URL
Published Aug 25, 2026 · Updated Aug 25, 2026
Stored cross-site scripting in Roxnor FundEngine 1.8.1 and earlier allows remote authenticated users to inject scripts into campaign pages. The video-URL REST path accepts wfp_featured_video_url without sufficient input sanitization or output escaping, then renders the stored value. Subscriber-level access reaches the endpoint because its permission callback unconditionally permits authenticated requests; the script executes when a user opens the injected page.
