CVE-2026-121515FV Flowplayer Video Player <= 7.5.56.7212 - Unauthenticated Stored Cross-Site Scripting via Comment Content
Medium 5.4
In plain English
A medium-severity cross-site scripting in FV Flowplayer Video Player from foliovision. There are no confirmed reports of exploitation so far.
Official description
The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 7.5.56.7212 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the 'Parse Vimeo and YouTube links' option to be enabled, and the injected comment must be approved before the script executes for site visitors.
