The XSS is in the timeline page displaying the workflow execution details of the workflow that was sent the crafted signal.\nAccess to send a signal to a workflow is determined by how you configured the authorizer on your server. This includes any entity with permission to directly call SignalWorkflowExecution or SignalWithStartWorkflowExecution, or any entity can deploy a worker that has access to call workflow progress APIs (specifically RespondWorkflowTaskCompleted).\n"
