CVE-2026-71459
Automation-controller: automation-controller-container: automation-controller: jobjobeventschildrensummary rbac bypass exposes cross-tenant job event tree structure
What happened?
JobJobEventsChildrenSummary view has no model/parent_model. ModelAccessPermission.check_get_permissions() falls through (returns True) for any authenticated user. The view uses raw get_object_or_404(Job, pk) without DRF object-level permission check. Zero-privilege user reads event tree structure, event_processing_finished status, and enumerates Job IDs platform-wide via 200/404 oracle. Sibling endpoint /jobs/{id}/job_events/ correctly returns 403.
