EPSS Percentile

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'synopsis' Shortcode Attribute in all versions up to, and including, 7.5.54.7212 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' (parse_comments) option to be enabled and the liststyle attribute set to "season" for the vulnerable code path to be reached.
