CVE-2026-84720

MediumCVSS 6.5
Published: Updated: Translated: NVD NIST

Summary

In Ansible Automation Platform automation-controller, the WorkflowJobNode.ancestor_artifacts database column, storing raw merged set_stats artifacts propagated between workflow nodes, is not wrapped in prevent_search() and is accepted for arbitrary field lookups by the REST filter backend, even though it is omitted from the API serializer. Because the column is persisted before Ansible's no_log masking is applied, a user with read access to a workflow can use the result count as an oracle to recover, character by character, values marked no_log.

Risk Assessment

An attacker can recover secrets marked no_log by the playbook author, including across organizations, breaching data confidentiality. Read access to a workflow or access via the credential-types endpoint suffices.

Recommendation

Upgrade Ansible Automation Platform to a version containing the fix. Restrict workflow read access and verify the column is wrapped in prevent_search().

Original NVD description (English source)

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