CVE-2026-67611: OpenEMR 8.2.0 OAuth2 Password Grant Authentication Bypass via SMART Configuration
Noroxi assessment
Priority: Monitor (action score 34/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.78% (FIRST EPSS); higher than 56.5% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
