Summary

The FV Flowplayer Video Player plugin for WordPress, by Foliovision, is affected in all versions up to and including 7.5.56.7212. Improper input sanitization and output escaping of the 'comment' parameter (CWE-79) let an unauthenticated attacker store arbitrary web scripts. The scripts run when a user opens an affected page, but only if the 'Parse Vimeo and YouTube links' option is enabled and the injected comment is approved.

Description from the CNA

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.
