Overview

vp-toolkit is a TypeScript/JavaScript API generating and signing w3c verifiable credentials and related objects.

Affected versions of this package are vulnerable to Improper Access Control. The verifyVerifiablePresentation() method checks the cryptographic integrity of the verifiablePresentation.proof.n.verificationMethod, but it does not check if the credentialSubject.id matches the signer of the VP proof.
