CVE-2025-57817Network attack vector

Owner-level escalation via unchecked OAuth scope assignment

Published Sep 8, 2025 · Updated Sep 9, 2025

Missing authorization in Ethyca Fides before 2.69.1 allows remote authenticated users to gain owner-equivalent privileges via OAuth client scopes. The creation and update endpoints accept scopes present in SCOPE_REGISTRY without verifying that the requesting client already holds them. A contributor with client:create or client:update can assign arbitrary scopes and access user management, system configuration, and permission assignment.
