CVE-2026-84703

A flaw was found in Red Hat Ansible Automation Platform's automation-controller. When creating or editing an execution environment, the controller does not verify that the requesting user has use permission on the container registry credential referenced by the execution environment; it validates only the organization and the credential kind. An authenticated user who is an execution-environment admin of one organization can associate a container registry credential belonging to a different organization -- one they cannot otherwise read, list, or use -- to an execution environment they control. When a job runs with that execution environment, the controller decrypts the foreign credential's registry password and supplies it to the container runtime, disclosing another organization's registry credentials across the tenant boundary.
