CVE-2026-97398
El plugin FV Flowplayer Video Player para WordPress es vulnerable a Secuencias de comandos en sitios cruzados (XSS) almacenado mediante el atributo de shortcode 'synopsis' en todas las versiones hasta la 7.5.54.7212 inclusive, debido a una sanitización de entrada y un escapado de salida insuficientes. Esto permite que atacantes no autenticados inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página infectada. Para que se alcance el código vulnerable, es necesario que la opción 'Parse Vimeo and YouTube links' (parse_comments) esté habilitada y que el atributo liststyle esté establecido en "season".

"value": "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."
