Descriptions

The WordPress File Upload WordPress plugin before 4.23.3 does not sanitise and escape some of its settings, which could allow high privilege users such as contributors to perform Stored Cross-Site Scripting attacks.

El complemento WordPress File Upload de WordPress anterior a 4.23.3 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, como los contribuyentes, realizar ataques de Cross-Site Scripting almacenados.

The Wordpress File Upload plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link' attribute in versions up to, and including, 4.23.2 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.
