Summary

Nautobot is a Network Source of Truth and Network Automation Platform. From 3.0.0 until 3.1.8, the generic ApprovalWorkflowStageResponse create endpoint does not enforce approver-group membership, change permission on the object under review, or the one-response-per-user restriction applied by the intended approve and deny actions. A user with only extras.add_approvalworkflowstageresponse can submit approved responses directly, while writable user and state fields permit responses to be attributed to arbitrary users. These forged responses can satisfy min_approvers, approve the workflow, and activate its gated ScheduledJob without a legitimate approver. This issue is fixed in version 3.1.8.
