# CVE-2026-71459: Automation-controller: automation-controller-container: automation-controller: jobjobeventschildrensummary               rbac bypass exposes cross-tenant job event tree structure

Status: published. Published: 2026-09-23. Updated: 2026-11-05.

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.
