How to Fix GHSA-ff5x-w9wg-h275

To remediate this vulnerability, upgrade all affected Vp toolkit dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vp-toolkit fixed: 0.2.2 
npm install vp-toolkit@0.2.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls vp-toolkit

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-ff5x-w9wg-h275, inspect your project dependencies using npm:

npm ls vp-toolkit

Analyze the terminal output to locate any version of Vp toolkit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.2), your application is affected.

Note: The npm ls vp-toolkit command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Vp toolkit, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The [`verifyVerifiablePresentation()`](https://github.com/rabobank-blockchain/vp-toolkit/blob/master/src/service/signers/verifiable-presentation-signer.ts#L97) method check the cryptographic integrity of the Verifiable Presentation, but it does not check if the [`credentialSubject.id`](https://github.com/rabobank-blockchain/vp-toolkit-models/blob/develop/src/model/verifiable-credential.ts#L150) DID matches the signer of the VP proof. The **verifier** is impacted by this vulnerability. ### Patches Patch will be available in version 0.2.2. ### Workarounds - Compute the address out of the `verifiablePresentation.proof.n.verificationMethod` using `getAddressFromPubKey()` from `crypt-util@0.1.5` and match it with the `credentialSubject.id` address from the credential. ### References [Github issue](https://github.com/rabobank-blockchain/vp-toolkit/issues/14) ### For more information If you have any questions or comments about this advisory: * Discuss in the existing [issue](https://github.com/rabobank-blockchain/vp-toolkit/issues/14) * [Contact me](https://github.com/rabomarnix)
