Summary
OpenEMR before 8.5.0 contains a missing authorization vulnerability in several custom/ scripts that rely only on session authentication and never call AclMain::aclCheckCore(). Any authenticated low-privilege user can request export_labworks.php, chart_tracker.php, or export_registry_xml.php to disclose patient SSN, DOB, and insurance data or provider NPI/tax IDs, and forge chart-tracker records.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of openemr/openemr published their own advisory on GitHub. Reviewed sources take precedence over it.
