CVE-2022-3828 – Video Thumbnails <= 2.12.3 - Admin+ Stored XSS

https://notcve.org/view.php?id=CVE-2022-3828

The Video Thumbnails WordPress plugin through 2.12.3 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 Video Thumbnails de WordPress hasta la versión 2.12.3 no sanitiza ni escapa algunas de sus configuraciones, lo que podría permitir a usuarios con privilegios elevados, como el administrador, realizar ataques de Cross-Site Scripting (XSS) Almacenado incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en una configuración multisitio). The Video Thumbnails plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's settings in versions up to, and including, 2.12.3 due to insufficient input sanitization and output escaping. This makes it possible for administrator-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://wpscan.com/vulnerability/4188ed01-b64b-4aba-a215-e8dc5b308486 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
