OpenEMR before 8.5.0 contains an inverted comparison in Document::has_expired() that causes the FHIR Binary download endpoint to treat time-limited PHI documents as unexpired after their one-hour lifetime. Authenticated users still authorized for a Binary/{id} resource can download expired bulk export NDJSON files and $docref CCDs indefinitely.

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.
