CVE-2026-97398

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unquoted popup shortcode attribute in all versions up to and including 7.5.54.7212 due to insufficient input sanitization and output escaping. This allows authenticated attackers with subscriber-level access and above to inject arbitrary web scripts that execute whenever a user accesses an injected page. Successful exploitation requires the profile_videos_enable_bio option to be enabled, as script execution occurs on the author bio/archive page where the profile-video shortcode is rendered.

The FV Flowplayer Video Player WordPress plugin (up to version 7.5.54.7212) fails to properly neutralize input during web page generation, enabling Stored XSS. Malicious JavaScript can be persistently stored and executed in a user's browser.

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'video_player' shortcode 'align' attribute in all versions up to and including 7.5.51.7212 due to insufficient input sanitization and output escaping.
