CVE-2026-115573
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/classes/Controller.class.php allows explicit controller.php dispatch to controllers missing from CONTROLLER_ACL_MAP, and checkControllerAcl() returns without enforcing any permission for those entries. A low-privilege authenticated user can invoke C_X12Partner::edit_action_process() to create or alter insurance-routing hosts and credentials, or invoke C_PatientFinder::find_action_process() to enumerate patient names, dates of birth, and identifiers. The shared fail-open dispatcher root cause also exposes other administrative controllers that were intended to be reached through ACL-gated Practice Settings routes. This issue is fixed in version 8.3.0.

Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
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.
