CVE-2025-68428 - jsPDF is a library to generate PDFs in JavaScript

CVE-2025-68428 + jsPDF is a library to generate PDFs in JavaScript + High + 2026-01-05

One-sentence business risk

Filesystem escape can disclose secrets or overwrite trusted files, turning a dependency bug into host or account compromise.

Research notes

  • Root cause: jsPDF is a library to generate PDFs in JavaScript.
  • Affected versions: Prior to version 4.
  • Fixed / safe versions: version 4.0.0.
  • Public exploit / PoC signal: the consulted NVD/GHSA/vendor sources describe the trigger class; treat it as reproducible until patched.
  • CVSS: 7.5 CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N.

Exact vulnerable code pattern

target = join(base_dir, user_path); read_or_write(target)

Fixed / mitigated code pattern

target = realpath(join(base_dir, user_path)); assert target is inside realpath(base_dir)

Dependency or runtime update:

npm ls node || true
npm install node@latest --save-exact
npm audit --omit=dev

Step-by-step integration guide

  1. Inventory node across source, lockfiles, SBOMs, container images, CI images, and deployment manifests.
  2. Upgrade to version 4.0.0 or apply the exact vendor patch referenced below.
  3. Replace the vulnerable path-traversal pattern with the fixed pattern and fail closed on malformed input.
  4. Add a regression test that exercises the advisory trigger and proves the request is rejected, bounded, or authorized.
  5. Deploy through canary, monitor security logs and resource metrics, then remove temporary edge blocks only after all runtimes are fixed.

Alternative mitigations

  • Disable the vulnerable feature path while the package/runtime update rolls out.
  • Add WAF or reverse-proxy rules for traversal tokens, prototype-polluting keys, oversized frames, shell metacharacters, or unauthenticated tool calls matching the trigger class.
  • Restrict internal egress, rotate exposed secrets, and revoke affected tokens/keys if the vulnerability can disclose config, logs, JWT secrets, proxy credentials, or PKI material.
  • For admin/API authorization issues, temporarily require elevated roles and explicit ownership checks at the gateway.

Copy-paste skill

You are remediating CVE-2025-68428 (jsPDF is a library to generate PDFs in JavaScript) in this repository.

Find every affected dependency, runtime, image, service configuration, and reachable code path. Upgrade or patch to version 4.0.0. Replace the vulnerable path-traversal pattern with a fail-closed implementation, add a regression test for the trigger shape, and update deployment/SBOM artifacts. If this repository does not control the affected runtime, create TRIAGE.md naming the owner, affected version, fixed version, and blocking decision.
