Technical details

The Editor component in Kendo UI for Vue fails to properly sanitize unsafe URLs in the Insert Link and Insert Image dialogs, allowing an authenticated attacker to inject JavaScript-based URIs (such as javascript: or data: schemes). When a user clicks the resulting link or loads the image, the malicious script executes in their browser context, achieving stored or reflected XSS depending on deployment. The vulnerability affects versions 2.7.1 through 10.0.0.
