CVE-2025-13772Network attack vectorHinoki check available

Authenticated AI settings access via unchecked namespace identifier

Published Jan 9, 2026 · Updated Jan 9, 2026

Missing authorization in GitLab EE allows remote authenticated users to access other namespaces' AI model settings through the Duo Workflows API. The find_root_namespace helper accepts a caller-controlled query parameter or X-Gitlab-Namespace-Id header and calls find_namespace, which returns a namespace without checking the user's access. A valid account and network access to the API are required; the flaw exposes and permits use of another namespace's model configuration but does not grant broader namespace access.
