DescriptionGitHub Advisory

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, the encounter vitals API accepts an id in the request body and treats it as an UPDATE. There is no verification that the vital belongs to the current patient or encounter. An authenticated user with encounters/notes permission can overwrite any patient's vitals by supplying another patient's vital id, leading to medical record tampering. Version 8.0.0.2 fixes the issue.

AnalysisAI

OpenEMR versions prior to 8.0.0.2 contain an authorization bypass vulnerability in the encounter vitals API that allows authenticated users with encounters/notes permissions to overwrite any patient's vital signs by supplying another patient's vital ID in the request body. This constitutes medical record tampering with integrity implications rated CVSS 6.5. …

Vulnerability AssessmentAI

Risk Assessment The CVSS 6.5 score reflects medium severity with network accessibility (AV:N), low attack complexity (AC:L), and required low-privileged authentication (PR:L), but the integrity impact is high (I:H) and confidentiality/availability are not affected. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A healthcare administrative user with valid encounters/notes permissions authenticates to the OpenEMR web interface or API. The attacker discovers the vital record ID of a patient they do not have authorization to modify (e.g., via previous API reconnaissance or information disclosure). …
Remediation Upgrade OpenEMR immediately to version 8.0.0.2 or later as the primary remediation. … Detailed patch versions, workarounds, and compensating controls in full report.
