CVE-2026-12473
OHIF Viewers DICOM Server-Side request forgery
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.
