No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenEMR through 8.2.0 contains an authentication bypass vulnerability that allows attackers with valid credentials to circumvent multi-factor authentication by exploiting the exposed OAuth2 password grant flow through an unauthenticated client registration endpoint. Attackers can register an OAuth2 client via the unauthenticated registration endpoint and use the password grant to exchange credentials for an API access token, bypassing the normal web interface authentication and any enforced multi-factor authentication controls.
