OpsTree REMS through 1.0.0 contains an improper authorization vulnerability that allows authenticated users to set an incident's reporter to another user by supplying a client-controlled reporter field. Attackers can send crafted POST /api/v1/incidents or PATCH /api/v1/incidents/{id}/status requests to falsify incident attribution and corrupt the accountability audit trail.
