Summary
OpenEMR before 8.5.0 contains an improper authorization vulnerability in interface/orders/order_manifest.php, which checks patients/med without requiring write access or applying patient squad restrictions. Users with only patients/med view permission can request any order ID to read squad-restricted patient data and submit bn_save and form_omit parameters, without a CSRF token, to set do_not_send flags that suppress ordered lab procedures.

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.
