Description
OpenEMR before 8.3.0 contains missing authorization and insecure direct object reference vulnerabilities in the oe-module-prior-authorizations module that allow authenticated low-privilege users to access and modify other patients' records. Attackers can request public/reports/list_report.php to view all patients' names, MRNs, insurance and prior-auth data, or submit arbitrary id values to public/index.php to overwrite other patients' prior-authorization records.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-124456. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
