Authenticated credential disclosure via missing field authorization

Published Jul 27, 2025 · Updated Jul 28, 2025

Improper access control in ChanCMS 3.1.0 through 3.1.2 allows remote authenticated users to read stored access and secret keys. The /sysApp/find handler includes accessKey and secretKey fields in its response without enforcing field-level authorization. A low-privileged authenticated account can retrieve credential material remotely; no integrity or availability impact is established.
