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.

Fixes

Solution

The maintainer has fixed the reported vulnerability and released version 3.12.2 (2026-05-18). The fix is located at OHIF/Viewers#5985 (master), OHIF/Viewers#5978 (release/3.12). Users are recommended to upgrade to v3.12.2 or later. Operators who need dicomwebproxy or dicomjson in authenticated deployments must additionally configure the new dangerouslyAllowedOriginsForAuthenticatedEnvironments allowlist in app-config.js.


Workaround

Users running OHIF with authentication should remove ALL unused DicomWebProxyDataSource and DicomJSONDataSource configurations from the configuration file they are deploying with.
