This vulnerability is a broken access control issue in Turms IM Server v0.10.0-SNAPSHOT and earlier. Specifically, the handleQueryUserOnlineStatusesRequest() method in UserServiceController.java allows any authenticated user to query the online status, device information, and login timestamps of arbitrary users without proper authorization checks.

Impact Analysis

This vulnerability can impact you by allowing unauthorized access to sensitive user information such as online status, device details, and login timestamps. This could lead to privacy violations, user tracking, and potential misuse of personal data by malicious actors within the system.
