Published: 06/08/2026(UTC)Updated: 06/08/2026(UTC)Translated: 06/08/2026(UTC)NVD NIST

Summary

In Apache CXF's OAuth2 Dynamic Client Registration endpoint, the authorization server accepts and stores the `scope` value supplied in the client registration request verbatim, without validating it against an AS-defined allowlist. This could lead to a client self-assigning privileged scopes at registration time. Users are advised to upgrade to versions 4.2.3, 4.1.8, or 3.6.12.

Risk Assessment

Risk of clients self-assigning privileged scopes, potentially leading to unauthorized access to protected resources.

Recommendation

Upgrade Apache CXF to versions 4.2.3, 4.1.8, or 3.6.12, which fix this vulnerability.
