CISA Malcolm

What happened

This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external site. Successful exploitation could allow an attacker to act with the compromised user's session privileges within the application.
