https://notcve.org/view.php?id=CVE-2024-0559

The Enhanced Text Widget WordPress plugin before 1.6.6 does not validate and escape some of its Widget options before outputting them back in attributes, 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 Enhanced Text Widget de WordPress anterior a 1.6.6 no valida ni escapa algunas de sus opciones de widget antes de devolverlas en atributos, 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 Enhanced Text Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widget options in all versions up to, and including, 1.6.5 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled. • https://research.cleantalk.org/cve-2024-0559 https://wpscan.com/vulnerability/b257daf2-9540-4a0f-a560-54b47d2b913f • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
