## Technical details

An improper authorization vulnerability (CWE-863/CWE-285) exists in WukongCRM up to version 11.3.3 within the PermissionServiceImpl.java component of the URL Handler. The flaw is a logical bypass that can be triggered by manipulating URL paths (e.g., using path traversal-like sequences such as '///;name=/v2/api-docs'). A remote attacker with low-level authenticated access can exploit this to perform unauthorized actions, specifically querying the full user list to obtain user IDs and subsequently resetting passwords for arbitrary accounts. While the vendor was notified, no official patch has been confirmed at the time of disclosure, and public exploits are available.
