CVE-2026-62324
Jodit has incomplete javascript: scheme normalization in sanitizeHTMLElement href check that allows link XSS
Description
Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. Prior to 4.12.31, Jodit's sanitizeHTMLElement method fails to use isDangerousUrl to normalize javascript: href values before checking the scheme, allowing case variants, control-byte prefixes, and embedded tabs or newlines to bypass filtering and execute attacker-controlled script when a victim clicks a stored link rendered by an application. This issue is fixed in version 4.12.31.

Action Type Old Value New Value Added Translation Title: jodit de xdan, Description: Jodit Editor es un editor WYSIWYG con un navegador de archivos integrado y editor de imágenes. Antes de la versión 4.12.31, el método sanitizeHTMLElement de Jodit no utiliza isDangerousUrl para normalizar los valores href de javascript_disabled: antes de verificar el esquema, lo que permite que variantes de mayúsculas y minúsculas, prefijos de bytes de control y tabulaciones o saltos de línea incrustados eludan el filtrado y ejecuten scripts controlados por el atacante cuando una víctima hace clic en un enlace almacenado renderizado por una aplicación. Este problema está solucionado en la versión 4.12.31. -
