CVE-2026-12473: Open Health Imaging Foundation Ohif Dicom Web Viewer Framework

High severity, CVSS 8.2. EPSS: 0.4% chance of exploitation in the next 30 days.

Two data sources (DICOMWebProxy and DICOMJSON) shipped in the default configuration fetch an arbitrary URL parameter without validation. A global authentication service in OHIF automatically injects the authenticated user's OIDC Bearer token into the resulting requests, sending it to the attacker-controlled server. DICOMweb data sources are not impacted.

Affected products

• Open Health Imaging Foundation Ohif Dicom Web Viewer Framework: up to and including v3.12.0
