A security flaw has been discovered in Stirling-Tools Stirling-PDF up to 3.3.0. Affected is the function WorkflowParticipantController.getParticipantDetails of the file app/proprietary/src/main/java/stirling/software/proprietary/workflow/controller/WorkflowParticipantController.java of the component Participant Details Endpoint. Performing a manipulation results in insufficient session timeout value. Remote exploitation of the attack is possible. The vendor was contacted early about this disclosure but did not respond in any way.
