CVE-2026-12135: Foliovision Fv Flowplayer Video Player

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

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 on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
