Official Description
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}.
Technical Analysis
CVE-2020-27358 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
