The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1.5 (and 7.5.1 for the Pro version) due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Esto hace posible que atacantes autenticados, con permisos de nivel de administrador y superiores, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. Esto solo afecta a las instalaciones multisitio y a las instalaciones en las que se ha deshabilitado unfiltered_html."
