CVE-2026-110531 · Package
NO FIX YET · SEE WHAT TO DO
The FV Player 8 plugin for WordPress does not sanitize the 'fv_player_videos' parameter, so logged-in subscribers can save scripts into pages. Those scripts run in the browser of any user who opens the injected page.

Sites running FV Player 8 up to and including 8.1.9 where the "Allow visitors to upload videos to their profile" setting is turned on, since the vulnerable save routine is otherwise closed to subscribers. Sites without that setting enabled, or running a newer version, can skip it.

8.1.9 are affected.The FV Player 8 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fv_player_videos' parameter in all versions up to, and including, 8.1.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the administrator-controlled "Allow visitors to upload videos to their profile" setting to be enabled, without which the vulnerable save routine is inaccessible to Subscriber-level users.
