A template injection vulnerability was discovered in the Dashboards functionality due to improper validation of an input parameter. An authenticated user with the required privileges can define a dashboard containing a malicious payload, or a victim can be socially engineered into importing a malicious dashboard. When the victim views or imports the dashboard, the payload executes in their browser context, allowing the attacker to modify application data or disrupt application availability.
