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.
