When another authenticated user selects the stored action from Event Actions and selects Continue, attacker-controlled JavaScript runs in the browser of that user. This could expose data or actions available through Splunk Web to that user. The vulnerability is possible because Dashboard Studio does not sufficiently validate workflow-action URLs before processing them. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the \"power\" Splunk role should not be able to exploit the vulnerability at will.
