Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A prototype pollution vulnerability exists in the function copy in dom.js in the xmldom (published as @xmldom/xmldom) package before 0.8.3 for Node.js via the p variable. NOTE: the vendor states "we are in the process of marking this report as invalid"; however, some third parties takes the position that "A prototype injection/Prototype pollution is not just when global objects are polluted with recursive merge or deep cloning but also when a target object is polluted."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

@xmldom/xmldom version 0.8.3 or later

  1. 1. Identify the current installed version of @xmldom/xmldom by checking package.json or running 'npm list @xmldom/xmldom'
  2. 2. If running version < 0.6.0, upgrade to 0.7.6 or later (preferably 0.8.3)
  3. 3. If running version >= 0.7.0 and < 0.7.6, upgrade to 0.7.6
  4. 4. If running version >= 0.8.0 and < 0.8.3, upgrade to 0.8.3
  5. 5. If running version 0.9.0, upgrade to a version >= 0.8.3 (check for latest stable release)
  6. 6. Run 'npm install @xmldom/[email protected]' or the appropriate version
  7. 7. Test the application thoroughly to ensure XML parsing functionality still works correctly
  8. 8. Re-deploy the updated application
Caveat Verify compatibility if upgrading from very old versions (< 0.6.0); review changelog for any breaking changes between your version and 0.8.3
