CVE-2026-49773Network attack vector

Stored XSS via profile-video ad and popup content

Published Jun 15, 2026 · Updated Jun 15, 2026

Stored XSS in FolioVision FV Flowplayer Video Player before 7.5.51.7212 allows remote authenticated users to execute JavaScript. When Enable profile videos is active, the profile-video storage path accepts video ad and popup content without neutralizing executable markup. Subscriber access is sufficient to save the payload, but another user must view the affected content; the script then runs in that viewer's browser context.
