{"schemaVersion":3,"id":"CVE-2026-84720","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in the Ansible Automation Platform automation-controller. 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.","dates":{"published":"2026-09-23T19:40:36.979Z","modified":"2026-10-16T11:55:22.643Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00271,"percentile":0.1813,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-24T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00271,"percentile":0.1813}],"last30":[{"date":"2026-09-24T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00271,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00271,"percentile":0.1813}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"e
