Descriptions

The Photospace Responsive plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘psres_button_size’ parameter in versions up to, and including, 2.1.1 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.

El complemento Photospace Responsive para WordPress es vulnerable a Cross-Site Scripting (XSS) Almacenado a través del parámetro 'psres_button_size' en versiones hasta la 2.1.1 incluida debido a una sanitización de entrada y un escape de salida insuficientes. 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.
