Descriptions

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wp_id' parameter in all versions up to, and including, 4.4.2 due to missing authorization checks on processAction function, as well as insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that will execute whenever a user accesses a wp-admin dashboard.

El complemento Online Booking & Scheduling Calendar for WordPress by vcita para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del parámetro 'wp_id' en todas las versiones hasta la 4.4.2 incluida debido a la falta de controles de autorización en la función ProcessAction, así como como una higienización insuficiente de los insumos y fugas de productos. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios que se ejecutarán cada vez que un usuario acceda a un panel de administración de wp.
