Descriptions

The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'advanced_iframe' shortcode in versions up to, and including, 2023.8 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 Advanced iFrame para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del shortcode 'advanced_iframe' en versiones hasta la 2023.8 incluida debido a una sanitización de entrada insuficiente y 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.
