CVE-2025-11821
Full vulnerability record from the local CVENow database.
Description
The Woocommerce – Products By Custom Tax plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'woo_products_custom_tax' shortcode in all versions up to, and including, 2.2. This is 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.

"value": "El plugin Woocommerce - Products By Custom Tax para WordPress es vulnerable a cross-site scripting almacenado a través del shortcode 'woo_products_custom_tax' en todas las versiones hasta la 2.2, inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos proporcionados por el usuario. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
