Summary

The FV Flowplayer Video Player plugin for WordPress, in all versions up to and including 7.5.55.7212, does not sanitize input or escape output of the fv_player_videos[_fv_player_user_video][] parameter, which is a missing input neutralization flaw (CWE-79). An authenticated attacker with Subscriber-level access or above can store arbitrary web scripts that run in a user's browser when that user opens an injected page. The flaw requires an administrator to have enabled the profile video upload setting before Subscriber-level users can submit profile videos.

Description from the CNA

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fv_player_videos[_fv_player_user_video][]' parameter in all versions up to, and including, 7.5.55.7212 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 an administrator to have enabled the "Allow visitors to upload videos to their profile" (profile_videos_enable_bio) setting before Subscriber-level users can submit profile videos.
