CVE-2026-124483 Nov 8, 2026 Source: Vendor
OpenEMR before 8.4.0 contains an incorrect authorization vulnerability because the prescription REST API routes check the patients.med ACL instead of patients.rx and request no specific permission bit, so read-only Medical/History access passes the check. Authenticated staff users can reuse the UI-exposed APICSRFTOKEN to enumerate prescription UUIDs, forge prescriptions for arbitrary patients, and deactivate existing prescriptions tenant-wide.
