Descriptions

A stored XSS vulnerability in the Visualizer plugin 3.3.0 for WordPress allows an unauthenticated attacker to execute arbitrary JavaScript when an admin or other privileged user edits the chart via the admin dashboard. This occurs because classes/Visualizer/Gutenberg/Block.php registers wp-json/visualizer/v1/update-chart with no access control, and classes/Visualizer/Render/Page/Data.php lacks output sanitization.

Una vulnerabilidad de tipo XSS almacenada en el plugin Visualizer versión 3.3.0 para WordPress, permite a un atacante no autenticado ejecutar JavaScript arbitrario cuando un administrador u otro usuario privilegiado edita la tabla por medio del panel de administración. Esto ocurre porque classes/Visualizer/Gutenberg/Block.php registra wp-json/visualizer/v1/update-chart sin control de acceso, y classes/Visualizer/Render/Page/Data.php carece de saneamiento de la salida.
