Technical details

The PrivacyController endpoint at /privacy lacks ownership checks when processing GET and POST requests with a target uid parameter. An authenticated attacker can supply arbitrary user IDs to invoke PrivacyServiceImpl methods (getPrivacySetting, updatePrivacySetting) that directly query and modify the UserPrivacy table without verifying the requesting user owns that record. This is a classic insecure direct object reference (IDOR) flaw.
