Technical details
An insecure direct object reference (IDOR) vulnerability exists in the POST /api/v1/Import endpoint, which accepts a caller-controlled attachmentId parameter without verifying authorization. An authenticated attacker with Import scope access can reference an attachment ID belonging to another user, and after creating an Import record, call the error export endpoint to copy the original attachment's data into a new CSV owned by the attacker. This requires knowledge of the target attachment ID and authentication to the system.
