Description

Cross-Site Scripting (XSS) in the Chat component (@progress/kendo-angular-conversational-ui) in Progress Software Kendo UI for Angular versions prior to 25.3.0 allows a low-privileged attacker who can supply Chat messages to execute arbitrary JavaScript in another user's browser via an unsafe URL in an openUrl quick action, which runs when the user clicks the action.
