Alert meAnalysisAI
OpenEMR versions prior to 8.0.0 allow any authenticated user to view all internal messages and notes from other users by exploiting insufficient authorization checks on the Message Center's show_all parameter. The vulnerability exists because the application does not verify administrator privileges before returning the complete message list, enabling unauthorized disclosure of sensitive medical communications. Public exploit code exists for this medium-severity information disclosure vulnerability.
RemediationAI
A vendor patch is available — apply it immediately. Restrict network access to the affected service where possible.
