CVE-2026-84643 is a missing-authorization vulnerability in Red Hat Ansible Automation Controller Project signature validation. The Project signature-validation credential foreign-key relationship does not enforce the required use_role authorization check. A user can therefore bind a credential belonging to a different organization to a Project and cause that credential to be used for signature validation.
