DescriptionGitHub Advisory

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, five insurance company REST API routes are missing the RestConfig::request_authorization_check() call that every other data-modifying route in the standard API uses. This allows any authenticated API user to create and modify insurance company records even if their OpenEMR user account does not have administrative ACL permissions. Version 8.0.0.3 patches the issue.

AnalysisAI

OpenEMR versions prior to 8.0.0.3 allow authenticated API users to bypass administrative access controls on five insurance company management REST API endpoints due to missing authorization checks. An attacker with valid API credentials but non-administrative OpenEMR privileges can create, read, and modify insurance company records without proper permission validation. …
