Original NVD description (English source)
CamaleonCMS version 2.9.2 and earlier contains a missing authorization vulnerability in the admin users controller that allows any authenticated user to access any other user's profile data by supplying an arbitrary user ID parameter. Attackers can send a GET request to the admin profile endpoint with an enumerable sequential integer user ID to disclose profile information of any user, including administrators, due to the profile action being excluded from the role validation filter with no compensating ownership check.
