  "title": "Authorization bypass via direct object reference in Matchpoint API",
  "summary": "TPC Software Matchpoint's API does not adequately authorize requests that select another user through the `actingasuser` header. An attacker able to submit API requests and identify target user records may access sensitive information or perform actions on other accounts.",

Restrict API access to trusted users and networks until the vendor provides a fixed release; no fixed version is recorded.",
