Technical details

The vulnerability stems from improper path concatenation when the Quarkus framework applies authorization rules to management endpoints (CWE-862: Missing Authorization). Security policies intended for specific management paths are incorrectly combined with the management root path, causing authorization checks to be applied to the wrong internal paths. An attacker with local access can exploit this to bypass authorization and access management data or perform unauthorized configuration changes.
