Detailsinfo

A vulnerability was found in OHIF Viewers up to 3.12.14/3.13.6/3.14.0-beta.18. It has been rated as problematic. This issue affects some unknown processing of the file extensions/dicom-pdf/src/getSopClassHandlerModule.js of the component dicom-pdf extension. The manipulation of the argument MIMETypeOfEncapsulatedDocument with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. The summary by CVE is:

OHIF Viewers is a zero-footprint DICOM viewer with shared extension packages. From 3.5.0-beta.0 until 3.12.15, 3.13.7, and 3.14.0-beta.19, the dicom-pdf extension reads the attacker-controlled MIMETypeOfEncapsulatedDocument value in extensions/dicom-pdf/src/getSopClassHandlerModule.js and uses it as the Blob media type for the attacker-controlled EncapsulatedDocument bytes. When a victim opens Encapsulated PDF SOP Class 1.2.840.10008.5.1.4.1.1.104.1, extensions/dicom-pdf/src/viewports/OHIFCornerstonePdfViewport.tsx embeds the Blob URL in an object element. A Blob labeled as HTML is handled as HTML despite the application/pdf object hint, and the Blob inherits the OHIF origin, allowing embedded script to access session storage, authentication tokens, and same-origin PACS requests. The malicious DICOM object may be opened locally, uploaded to a shared PACS, or supplied by a DICOMweb source. This issue is fixed in source versions 3.12.15, 3.13.7, and 3.14.0-beta.19.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-118670 since 10/28/2026. The exploitation is known to be easy. The attack may be initiated remotely.
