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.</p> <p>Nautobot is a Network Source of Truth and Network Automation Platform.

Primary impact - self-approval: The approver checks (approver-group membership, `change` permission on the object under review, one-response-per-user) are enforced only in the `approve`/`deny` actions on `ApprovalWorkflowStage`. The generic `ApprovalWorkflowStageResponse` create endpoint enforces none of them, so a user holding only `extras.add_approvalworkflowstageresponse` can `POST` approved responses directly and drive a stage past its `min_approvers` threshold with no legitimate approver involved. The serializer also exposes `user` and `state` as writable, letting the attacker attribute responses to arbitrary users.</p> <p>2. Escalated impact job activation: Because the approval workflow gates a `ScheduledJob`, self-approval does not stop at the approval record. Stage approval cascades through `ApprovalWorkflow.save()` to `on_workflow_approved()`, which sets the target job to enabled/active.</p> <p>### Patches</p> <p>Fixed in Nautobot v3.1.8</p> <p>### Workarounds Restrict the `extras.add_approvalworkflowstageresponse` permission so that no untrusted user holds it; approval responses should only ever be created via the stage `approve`/`deny` actions. There is no configuration flag that disables the generic create endpoint prior to the patch.</p> <p><strong>Affected:</strong> PyPI: nautobot</p> <p>### Impact This is an authorization bypass that escalates into unauthorized server-side job execution.</p> <p>1.
