CVE-2023-6591 – Popup Box Pro < 20.9.0 - Admin+ Stored XSS

https://notcve.org/view.php?id=CVE-2023-6591

The Popup Box WordPress plugin before 20.9.0 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed El complemento Popup Box de WordPress anterior a 20.9.0 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, como el administrador, realizar ataques de Cross-Site Scripting incluso cuando unfiltered_html no está permitido. The Popup Box Business and Developer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions 20.0.0 to 20.9.0 (Developer) and versions 7.0.0 to 7.9.0 (Business) 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. Please note this affects the premium version of the plugin despite the shared slug. • https://wpscan.com/vulnerability/f296de1c-b70b-4829-aba7-4afa24f64c51 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
