CVE-2026-84720

*** Pendiente de traducción *** A flaw was found in the Ansible Automation Platform automation-controller. The<br /> WorkflowJobNode.ancestor_artifacts database column, which stores the raw merged set_stats<br /> artifacts propagated between workflow nodes, is not wrapped in prevent_search() and is therefore<br /> accepted for arbitrary field lookups by the REST filter backend, even though it is omitted from<br /> the API serializer. Because the column is persisted before Ansible&amp;#39;s no_log masking is applied,<br /> a user with only read access to a workflow — or, via a regular-expression lookup that bypasses<br /> the JSON cross-relation filter guard through the world-readable credential-types endpoint, any<br /> authenticated user with no roles — can use the result count as a boolean/count oracle to recover,<br /> character by character, secret values that a playbook author explicitly marked no_log, including<br /> across organizations.
