CVE-2026-104136
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the new_recall branch of interface/main/messages/save.php accepts a caller-supplied pid without enforcing patient-level or recall-workflow authorization. A low-privilege authenticated user who knows or enumerates a patient identifier can retrieve patient details, contact fields, HIPAA notification preferences, recent appointment information, and existing recall information. This issue is fixed in version 8.3.0.

Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
