An issue was discovered in REDCap 8.11.6 through 9.x before 10. The messenger’s CSV feature (that allows users to export their conversation threads as CSV) allows non-privileged users to export one another’s conversation threads by changing the thread_id parameter in the request to the endpoint Messenger/messenger_download_csv.php?title=Hey&thread_id={THREAD_ID}.
