Descriptions

The Easy Appointments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ea_full_calendar' shortcode in all versions up to, and including, 3.11.18 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.

El complemento Easy Appointments de WordPress es vulnerable a cross-site scripting almacenado a través del código corto 'ea_full_calendar' del complemento en todas las versiones hasta la 3.11.18 incluida debido a una sanitización de entrada insuficiente y a un escape de salida 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.
