CVE-2024-4756 – WP Backpack <= 2.1 - Admin+ Stored XSS

https://notcve.org/view.php?id=CVE-2024-4756

The WP Backpack WordPress plugin through 2.1 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 WP Backpack de WordPress hasta la versión 2.1 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 una configuración multisitio). The WP Backpack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.1 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. • https://wpscan.com/vulnerability/ce4688b6-6713-43b5-aa63-8a3b036bd332 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
