What is CVE-2026-110531?

The FV Player plugin for WordPress is susceptible to Stored Cross-Site Scripting due to inadequate input validation and output sanitization. This vulnerability is particularly exploited through the 'fv_player_videos' parameter in all versions up to and including 8.1.9. Authenticated attackers, starting from subscriber-level access, can inject arbitrary scripts into web pages. This becomes viable when the 'Allow visitors to upload videos to their profile' option is enabled, enabling access to the flawed save routine for the affected user roles.

Affected Version(s)

FV Player 8 0 <= 8.1.9
