Descriptions

The Broken Link Checker WordPress plugin before 1.11.20 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

El complemento de WordPress Broken Link Checker anterior a la versión 1.11.20 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con privilegios elevados, como el administrador, realizar ataques de cross site scripting almacenado incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en la configuración de múltiples sitios).

The Broken Link Checker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘youtube_api_key’ parameter in versions up to, and including, 1.11.19 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.
