An authorization bypass vulnerability exists in Apache Syncope allowing a delegated administrator to relocate a Realm subtree across administrative realm boundaries without proper permission. This affects Apache Syncope versions from 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.8, and 4.1.0-M0 through 4.1.3. Upgrading to versions 4.0.9 or 4.1.4 resolves this issue.
