CVE-2026-124456: OpenEMR before 8.3.0 Missing Authorization and IDOR in Prior-Authorizations Module

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: openemr openemr 8.3.0.

Low priority for now. Upgrade to openemr openemr 8.3.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org

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.
