The\nWorkflowJobNode.ancestor_artifacts database column, which stores the raw merged set_stats\nartifacts propagated between workflow nodes, is not wrapped in prevent_search() and is therefore\naccepted for arbitrary field lookups by the REST filter backend, even though it is omitted from\nthe API serializer. Because the column is persisted before Ansible's no_log masking is applied,\na user with only read access to a workflow — or, via a regular-expression lookup that bypasses\nthe JSON cross-relation filter guard through the world-readable credential-types endpoint, any\nauthenticated user with no roles — can use the result count as a boolean/count oracle to recover,\ncharacter by character, secret values that a playbook author explicitly marked no_log, including\nacross organizations.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:71114** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71114)\n- **RHSA-2026:71113** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71113)\n- **RHSA-2026:71179** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71179)\n- **RHSA-2026:71177** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.7 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71177)","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
