Summary

An insecure direct object reference (IDOR) vulnerability in the MatchPoint API relies on the `actingasuser` HTTP header without verifying the requester's authorization for the specified user. Manipulation of sequential identifiers allows access to personal, banking, and financial data, private messages, and physical-access QR codes, as well as modification of third-party accounts, password changes, impersonation, and virtual balance transfers.

Risk Assessment
