npm audit node-forge transitive dependency listhen

Not specified by the original author.

TL;DR

There is no version to upgrade to and no clean way to remove the package. As of 2026-10-12 the GitHub advisory GHSA-86w9-cpqp-85rv (CVE-2026-85393) lists node-forge at or below 1.4.0 as vulnerable with no first patched version, and 1.4.0 is still the latest release on npm. In a Nuxt app the chain is nuxt, then @nuxt/nitro-server, then nitropack, then listhen, then node-forge, and node-forge is a real listhen dependency (its HTTPS certificate work), not a stray lockfile entry. The working answers are: prove the vulnerable verification path is not reachable in your app, then either record a time-boxed audit exception with an expiry and a recheck trigger, or backport the unmerged upstream fix with patch-package or pnpm patch and pair it with the same exception, because scanners judge the version number and will keep flagging 1.4.0 either way. Do not run npm audit fix with the force flag and do not override node-forge to an older release: every published release is in the affected range.

node-forge
Severity: high
node-forge RSA PKCS#1 v1.5 signature verification accepts extra nested DigestAlgorithm elements - https://github.com/advisories/GHSA-86w9-cpqp-85rv
fix available via `npm audit fix --force`
  listhen depends on vulnerable versions of node-forge
    nitropack depends on vulnerable versions of listhen

Steps

1. Confirm the chain in your project. Run npm ls node-forge listhen nitropack nuxt. Expected: a single path showing nuxt at the top, then nitropack, then listhen, then node-forge at 1.4.0. If node-forge also appears under other parents (Expo tooling, acme-client, and code-signing packages are common ones), triage each path separately; this skill covers the Nuxt and listhen path.
2. Confirm there is nothing to upgrade to. Run npm view node-forge version and check the advisory page. Expected: npm reports 1.4.0 as the latest version, and the advisory lists the affected range as at or below 1.4.0 with no patched version. An npm override cannot fix this, because an override needs a safe target version and none exists; overriding to any older 1.x or 0.x release stays inside the affected range.
3. Check reachability before accepting any risk. The flaw is in RSA PKCS#1 v1.5 signature verification: node-forge accepts extra nested DigestAlgorithm elements, so a forged signature made with a low-exponent RSA key can pass verification. Ask two questions. First, does your own code import node-forge and verify signatures or certificates from outside parties with it? Search the repo for node-forge imports outside node_modules. Second, what does listhen use it for? listhen loads node-forge for generating self-signed HTTPS certificates for the local development server; it creates and signs its own certificate and does not verify RSA signatures supplied by an attacker. Expected finding for a standard Nuxt app: no application code path verifies an attacker-supplied signature with node-forge, and listhen is exercised by the dev server, not by request handling in a production build. If your app does verify outside signatures with node-forge directly, stop: do not accept the risk, apply the patch in step 5, and treat it as release-blocking.
4. Record a time-boxed audit exception, scoped to this one advisory. For pnpm, add the GHSA id under auditConfig ignoreGhsas in pnpm-workspace.yaml, with a comment naming the expiry date and the reason. For npm projects, use an allowlist tool such as audit-ci with GHSA-86w9-cpqp-85rv as the single allowlisted entry, or the equivalent single-advisory allowlist in your scanner (Trivy, Dependabot, or Snyk ignore with an expiry). Expected: the audit gate goes green for this advisory only, every other high or critical finding still fails the gate, and the exception carries an expiry 30 to 90 days out, not an open-ended ignore.
5. Optional, for teams that cannot accept the unpatched code: backport the upstream fix. The digitalbazaar forge repository has an open, unmerged pull request, number 1152, that rejects the extra elements inside the DigestInfo DigestAlgorithm sequence during verification. With npm, edit the installed package under node_modules, run npx patch-package node-forge, and commit the generated patch file plus a postinstall hook that reapplies it. With pnpm, run pnpm patch node-forge@1.4.0, apply the same change, then pnpm patch-commit and commit the result. Add a regression test that feeds a signature with extra nested DigestAlgorithm elements and asserts verification rejects it, while a valid signature still verifies. Expected: the test fails on the stock 1.4.0 install and passes with the patch. Note that scanners still flag version 1.4.0 after patching, so keep the step 4 exception and annotate it as patched locally.
6. Set the removal trigger now, while it is cheap. The exception and any local patch come out when one of these happens: a node-forge release above 1.4.0 ships with the fix, listhen releases a version that drops or upgrades node-forge, or Nuxt and nitropack update the listhen range. Recheck on the exception expiry date with npm view node-forge version and npm outdated listhen nitropack nuxt. Expected after a real fix ships: update the chain, delete the exception and the patch file, and npm audit reports no GHSA-86w9-cpqp-85rv finding.
7. Tell the security reviewer the right story in the pull request: this is an accepted, expiring exception for an advisory with no patched release, on a dependency whose vulnerable function is not reachable in the app, with the upstream fix tracked. Link the advisory and the upstream pull request. Expected: the reviewer can verify every claim in minutes instead of re-deriving that no upgrade exists.

When to use this skill

Use it when npm audit, pnpm audit, Dependabot, Trivy, or a CI security gate blocks on GHSA-86w9-cpqp-85rv or CVE-2026-85393 for node-forge in a Nuxt project, and the audit tree shows listhen and nitropack above node-forge. Also use it when a teammate proposes deleting node-forge, forcing the audit fix, or overriding the version and you need to show why none of those work yet.

When not to use this skill

Not for node-forge findings that arrive through a different parent where the vulnerable verification is actually called on outside data; that case needs the patch or a dependency change, not an exception alone. Not for the older node-forge advisories that do have patched releases (for example the ASN.1 issues fixed in 1.3.2 and later): upgrade instead. Not a reason to ignore future node-forge advisories; the exception covers exactly one GHSA id.

Variant phrasings

npm audit node-forge transitive dependency listhen

Same chain and same answer: the transitive path through listhen is the finding, and the triage above applies unchanged.

Nuxt security scan reports vulnerable transitive dependencies

Nuxt closed its tracking issue for these transitive findings as not planned, because the fix has to land in node-forge and listhen first. Treat it in the app, with the exception or patch above, rather than waiting on a Nuxt release.

Can I just remove listhen or node-forge from a Nuxt app

No supported removal exists while you keep the standard Nuxt and Nitro dev server: listhen declares node-forge as a regular dependency, so package-manager removal, manual lockfile edits, and empty overrides either regenerate on install or break listhen. Removing the whole Nuxt toolchain removes it, which is a migration decision, not an audit fix.

Why it happens

The advisory, published 2026-09-03, is an incomplete-fix follow-up: node-forge failed to validate the element count inside nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification, so garbage bytes can be embedded and signatures forged against low-exponent keys. Every release up to and including the latest, 1.4.0, is affected, and the upstream fix exists only as an open pull request. Framework trees surface it instantly because nitropack depends on listhen and listhen depends on node-forge, so one unpatched leaf turns the whole Nuxt audit red, and npm counts the finding once per package on the path.

Edge cases and pitfalls

• npm audit fix with the force flag: npm may offer to install a different major of an unrelated parent package; that change still ships node-forge 1.4.0 in most trees and adds a breaking migration on top. Read the offered install line before ever accepting it.
• Deleting the node_modules folder or hand-editing the lockfile: both regenerate on the next install and can break the dev server HTTPS path. Not a fix.
• Blanket audit ignores: an ignore with no GHSA scoping, no expiry, and no owner will silently cover the next, reachable node-forge flaw too. Scope it to the single advisory.
• Production-only audit runs: whether listhen shows up depends on where nuxt sits in your manifest (often devDependencies in app projects). A clean production audit does not clear a scanner that reads the full lockfile; align the exception with the tool that is actually blocking.
• Assuming the exception is the fix: it is a documented acceptance. The fix is a patched upstream release, and the expiry date is what forces the recheck.

Compatibility

Verified 2026-10-12 against the live npm registry and GitHub advisory database: node-forge latest 1.4.0 (affected at or below 1.4.0, no patched version), listhen 1.10.1 declaring node-forge ^1.4.0, nitropack 2.13.4 depending on listhen, and nuxt 4.6.1 shipping @nuxt/nitro-server on nitropack 2.13.4. Applies to npm and pnpm projects on Nuxt 3 and 4 whose tree contains the same chain. Re-verify the version facts before reusing after a new node-forge release ships.

npm supply chain: how to audit your lockfile

TL;DR

Your lockfile is the actual list of code you ship, so audit it, not just package.json. Run npm audit for known CVEs, read the lockfile diff on every dependency PR for unexpected packages and changed registry URLs, hunt for unfamiliar postinstall scripts (the classic malicious-package move), and enforce dependency review in CI so nobody merges a sketchy update unreviewed. Most supply-chain attacks arrive as boring-looking version bumps.

npm supply chain: how to audit your lockfile

Use this when

• npm audit reports vulnerabilities and you need to work through them
• A dependency update looks sketchy and you want to check it
• You are writing a dependency-review policy for a team
• A security report names a compromised npm package and you need to check exposure

Not for this skill when

• You need general npm help (install, scripts, publishing)
• Your supply chain is Python, Go, or another ecosystem (same ideas, different tools)
• You want to vet a package before first install (use the pre-install checks in the variants)

Steps

1. Run the audit and read it properly

npm audit

Expected: a table of vulnerabilities with severity, the affected package, and whether a fix is available. Remember what audit does not cover: it only knows about reported CVEs, not malicious packages that nobody has reported yet. A clean audit is not a clean bill of health.

2. Fix what is fixable, carefully

npm audit fix

Expected: the lockfile updates for non-breaking fixes. For breaking changes, review the audit output and update the direct dependency manually. Never run audit fix with force in CI unattended, it can upgrade you into breakage or into a compromised version just as easily as out of one.

3. Read the lockfile diff on every dependency PR

git diff package-lock.json | grep -E "^[+-].*(resolved|version)" | head -30

Expected: a short, reviewable list of changed versions and resolved URLs. Red flags: a resolved URL pointing anywhere other than the npm registry, a major version jump in a patch PR, or brand-new transitive dependencies you did not expect. This diff is where compromised-package updates are visible.

4. Hunt for unfamiliar install scripts

grep -o '"postinstall": "[^"]*"' package-lock.json | sort | uniq -c | sort -rn | head

Expected: a short list of postinstall scripts. Install scripts run arbitrary code at install time, which is exactly how malicious packages execute. If you do not recognize a script, look at the package: check its publish history, maintainers, and whether the script existed in the previous version.

5. Find out why a package is even there

npm ls [package-name]

Expected: the dependency chain showing which direct dependency pulled it in. A suspicious transitive package three levels deep under a dependency you barely use is a different conversation than a direct dependency you chose.

Variant: enforce review in CI

Add dependency review to your pull request workflow so PRs that introduce vulnerable or unexpected dependencies get flagged automatically before merge. Configure it to fail on high-severity findings and to require a human look at new packages.

Variant: vetting a package before first install

Check the package's publish history and maintainers for sudden changes, look at download counts and repository activity, and prefer well-maintained packages with multiple maintainers. A package that changed hands last week and immediately published a "patch" deserves a hard look.

Variant: npm audit signatures

Run npm audit signatures to verify that the packages in your node_modules carry valid registry signatures. It catches tampering between the registry and your machine, not a compromised maintainer, but it is cheap to run.

Why this happens

Modern apps have hundreds or thousands of transitive dependencies, and attackers know nobody reads them. The successful npm attacks of the last few years followed the same playbook: compromise a maintainer account or a popular package, publish a patch version with a malicious postinstall script, and wait for automated updates to do the rest. The lockfile diff is the cheapest place to catch it.

Edge cases and pitfalls

• npm audit is noisy about dev-only dependencies that never ship. Triage by what reaches production.
• False positives happen, especially with bundled or vendored copies. Confirm before burning a day.
• npm ci respects the lockfile exactly, npm install can update it. CI should always use npm ci.
• Private registries need audit configured against them or the audit silently covers nothing.
• Lockfile version matters. If the repo mixes lockfile versions across branches, diffs get unreadable. Standardize on one.
• A compromised package with no CVE will sail through npm audit. The diff review and script hunt are your backstop.

Tool notes: npm 9+ for current audit output. The dependency review action runs on GitHub Actions.

Thread query: npm supply chain: how to audit your lockfile

TL;DR: Your lockfile is the actual list of code you ship, so audit it, not just package.json.

Most supply-chain attacks arrive as boring-looking version bumps.

Not specified by the original author.

TL;DR

npm audit fix rewrites your dependency tree to apply security patches, and when it hits a peer-dependency conflict it dies halfway, leaving node_modules and the lockfile in a broken intermediate state. Restore both from git, reinstall clean, then apply the fixes selectively: bump the specific vulnerable packages yourself and resolve each ERESOLVE deliberately instead of letting audit fix guess.

The query

npm audit fix fails with "npm ERR! code ERESOLVE" and leaves the tree half-resolved

Use this when

• npm audit fix exits with ERESOLVE partway through
• node_modules or package-lock.json is left in a broken state after the run
• The audit report lists fixes you still need to apply

Not for

• ERESOLVE on a plain npm install (no audit fix involved)
• Audit fix completing but changing too much (review the diff, a different problem)
• Peer conflicts you introduced by hand-editing dependencies

Steps

1. Restore the tree to a known-good state

git checkout -- package-lock.json && rm -rf node_modules && npm ci

Expected output: a clean install matching the committed lockfile. Never try to repair the half-written tree; replace it.

2. List what audit actually wants

npm audit

Expected output: the vulnerability list with the recommended fix actions. You will apply these by hand, one at a time.

3. Fix the top vulnerabilities individually

For each fixable CVE, install the patched version of the specific package:

npm install [package]@[fixed-version]

Expected output: npm either resolves it or reports an ERESOLVE naming the exact peer conflict. One conflict at a time is debuggable; twenty at once is not.

4. Resolve each ERESOLVE deliberately

Read the peer conflict: which package demands the old peer, and is that demand real or stale? Options in order of preference: upgrade the demanding package too, add an override for the peer, or accept the vulnerability as a tracked exception.

Expected output: each conflict ends with a conscious decision recorded somewhere (commit message, ticket).

5. Verify the final tree

npm ls [package] && npm audit

Expected output: the tree is consistent (no ERESOLVE on install) and the audit count dropped by the fixes you applied. Commit the lockfile.

Variant phrasings

npm audit fix ERESOLVE half resolved tree

The short symptom search.

npm audit fix breaks node_modules peer dependency conflict

The cause-first search.

Compatibility: npm 7 and later, where peer dependencies are installed strictly and ERESOLVE is enforced.

Why it happens

npm audit fix is an automated tree rewriter: it computes a new tree with patched versions and applies it. Peer dependency constraints make some of those rewrites impossible, and npm aborts the operation after partially applying it. The half-resolved tree is not a corrupt state npm intended; it is the wreckage of an aborted rewrite.

Edge cases / pitfalls

• npm audit fix --force makes this worse, not better. It resolves conflicts by installing conflicting peer versions side by side, which usually breaks at runtime.
• Overrides (the overrides key) silence ERESOLVE but do not resolve the underlying incompatibility. Use them only when you have verified the combination works.
• If the vulnerable package is transitive, installing the fixed version directly adds it as a direct dependency. That is fine, but document why it is there.
• Some ERESOLVEs have no good answer: the fixed version genuinely conflicts with your stack. Then the fix is upgrading the stack or accepting the risk in writing, not fighting the resolver.
