CVE-2025-14548
Full vulnerability record from the local CVENow database.
Description
The Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'event_desc' parameter in all versions up to, and including, 1.3.16 due to insufficient input sanitization and output escaping. 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, granted they can convince an administrator to enable lower privilege users to manage calendar events via the plugin settings.

"value": "El plugin Calendar para WordPress es vulnerable a Stored Cross-site Scripting (XSS) a través del parámetro ’event_desc’ en todas las versiones hasta la versión 1.3.16 incluida, debido a una sanitización insuficiente de la entrada y a una fuga de escape en la salida. Esto permite que atacantes autenticados con nivel de Contribuidor o superior inyecten scripts web arbitrarios en páginas, los cuales se ejecutarán siempre que un usuario acceda a la página inyectada, siempre que logren convencer a un administrador para que permita a usuarios con privilegios menores gestionar eventos del calendario mediante la configuración del plugin."
