As published by the source; long descriptions are shortened.

dcmjs, a JavaScript library for DICOM manipulation used in web-based medical imaging viewers, contains an input validation bypass in its handling of DS (Decimal String) and IS (Integer String) value representations. The DecimalString and IntegerString classes in ValueRepresentation.js use a regex sanitizer followed by JavaScript's Number() constructor. While the regex strips direct NaN/Infinity strings, it preserves scientific notation (including the 'e' character), enabling: 1. Infinity injection via scientific notation overflow (1e999999) 2. NaN injection via sign-only remnants from stripped inf strings ("-inf" -> "-") 3. IS accepting scientific notation in violation of PS3.5 AFFECTED PRODUCT ================ Product: dcmjs (JavaScript DICOM manipulation library) Repository: https://github.com/dcmjs-org/dcmjs npm: https://www.npmjs.com/package/dcmjs Affected Versions: 100000) in violation of PS3.5 Section 6.2, which restricts IS to characters 0-9, +, -. (d) No range validation…

# Patch Next advisory brief: CVE-2026-46350

Advisory: dcmjs: DS/IS VALUE REPRESENTATION INPUT VALIDATION BYPASS
IDs: CVE-2026-46350, GHSA-px68-xx5g-48q5
Record: https://patchnext.com/advisories/cve-2026-46350 (revision 2, source checked 28 Oct 2026, 06:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: dcmjs 0.52.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm dcmjs: affected < 0.52.0; fixed in 0.52.0

## Suggested inspection (read-only)
- `npm ls dcmjs --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dcmjs.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
