Technical details
An insecure direct object reference (IDOR) vulnerability in the MatchPoint API allows attackers to bypass authorization by manipulating the `actingasuser` HTTP header without server-side verification of whether the requester has permission to access the specified user. Sequential user identifiers can be enumerated to systematically access arbitrary user accounts, their data, and perform account modifications including password changes and balance transfers. The vulnerability is network-reachable and requires no authentication or user interaction.
