Jodit has incomplete javascript: scheme normalization in sanitizeHTMLElement href check that allows link XSS

AI Analysis

No AI analysis yet.

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.
