Lifecycle Timeline
4DescriptionGitHub Advisory
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an authorization bypass vulnerability in the patient portal signature endpoint allows authenticated portal users to upload and overwrite provider signatures by setting type=admin-signature and specifying any provider user ID. This could potentially lead to signature forgery on medical documents, legal compliance violations, and fraud. The issue occurs when portal users are allowed to modify provider signatures without proper authorization checks. Version 8.0.0 fixes the issue.
AnalysisAI
OpenEMR versions prior to 8.0.0 contain an authorization bypass in the patient portal that allows authenticated users to forge provider signatures by uploading files with admin-signature type parameters for any provider. Public exploit code exists for this vulnerability, which could enable signature forgery on medical documents, creating legal and compliance risks. Upgrade to version 8.0.0 or later to remediate this high-severity flaw.
