Real-World Exposure

1 pkg affected
📦vp-toolkit

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

Impact

The verifyVerifiableCredential() method check the cryptographic integrity of the Verifiable Credential, but it does not check if the credential.issuer DID matches the signer of the credential.

The verifier is impacted by this vulnerability.

Patches

Patch will be available in version 0.2.2.

Workarounds

In case you trust certain issuers for certain credentials as a verifier, trust the issuer's public key from the credential.proof.verificationMethod field.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vp-toolkit. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update vp-toolkit to 0.2.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p94w-42g3-f7h4 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-p94w-42g3-f7h4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-p94w-42g3-f7h4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
