Technical details
A missing authorization control vulnerability in IBM Business Automation Workflow allows authenticated users to trigger import actions that should be restricted. The vulnerability affects both containerized and traditional deployments. An attacker who has valid authentication credentials can invoke import functionality without proper permission validation, potentially leading to unauthorized modification of workflow configurations or data. The fix requires implementing proper authorization checks on import operations.
