CVE-2022-1177Public exploitNetwork attack vector

Patient-report disclosure via missing ACL check

Published Mar 30, 2022 · Updated Aug 2, 2024

Incorrect authorization in OpenEMR before 6.1.0 allows remote authenticated users with accounting access to download patient reports. The custom report endpoint omits the patients/pat_rep ACL check, while default accounting ACLs grant patient-report access. An accounting-role session is sufficient to read patient reports that the role should not access.
