Descriptions

The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to, and including, 3.10 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

El complemento Media Library Assistant para WordPress es vulnerable a Cross-Site Scripting almacenado a través del código corto 'mla_gallery' en versiones hasta la 3.10 inclusive 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 permisos de nivel de colaborador y superiores inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
