dcmjs: DS/IS VALUE REPRESENTATION INPUT VALIDATION BYPASS
GitHub lists this reviewed advisory for dcmjs. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
dcmjs
source listed< 0.52.0
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: < 0.52.0 (patched in 0.52.0, released 2026-05-19) CVE: CVE-2026-46350 (assigned by GitHub 2026-05-13) CWE: CWE-20 (Improper Input Validation) CVSS Score: 7.5 (HIGH) CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H Maintainer note: Th

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
- vendor patch
The original advisory lists fixed boundaries 0.52.0 for dcmjs. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
