Technical details

The vulnerability is classified as an Insecure Direct Object Reference (IDOR) or Authorization Bypass Through User-Controlled Key (CWE-639) within the 'update-profile/' API endpoint. By supplying an arbitrary 'user_id' parameter in a network request, a remote, unauthenticated attacker can bypass authorization checks to retrieve JSON responses containing sensitive user data, specifically email addresses. The flaw stems from a failure to validate that the requesting user has the permission to view the profile associated with the provided ID. Patches were reportedly implemented in February and March 2026 for the respective systems.
