Technical details
The vulnerability is a stored XSS flaw in an unauthenticated endpoint that fails to sanitize and escape user-supplied content before displaying it on an admin page. An attacker can send malicious input through the unprotected post_notifications endpoint without authentication, and the payload persists in the application, executing when high-privilege users such as administrators access the admin interface. No known fix is currently available.
