Summary
OpenEMR before 8.5.0 contains a missing authorization vulnerability in authorizations_full.php that allows any authenticated staff user to authorize arbitrary patients' clinical records. Attackers can send a mode=authorize request with an attacker-chosen pid and their own CSRF token to set authorized=1 on billing, forms, pnotes, and transactions records, bypassing provider review.

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.
