CVE-2026-33918: Open-EMR Openemr

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the billing file-download endpoint `interface/billing/get_claim_file.php` only verifies that the caller has a valid session and CSRF token, but does not check any ACL permissions. This allows any authenticated OpenEMR user — regardless of whether they have billing privileges — to download and permanently delete electronic claim batch files containing protected health information (PHI). Version 8.0.0.3 patches the issue.

Affected products

• Open-EMR Openemr: before 8.0.0.3 (fixed in 8.0.0.3)
