Ursa CL-Signatures Revocation allows verifiers to generate unique identifiers for holders

Summary The revocation scheme that is part of the Ursa CL-Signatures implementations has a flaw that could impact the privacy guarantees defined by the AnonCreds verifiable credential model. Notably, a malicious verifier may be able to generate a unique identifier for a holder providing a...

Credentials Verification Bypass

vp-toolkit is vulnerable to credentials verification bypass. The verifyVerifiablePresentation function verifies the cryptographic integrity of the Verifiable Presentation but failure to check if the credentialSubject.id matches the signer of the VP proof allows to bypass the verification...

GHSA-FF5X-W9WG-H275 Holder can generate proof of ownership for credentials it does not control in vp-toolkit

Impact The verifyVerifiablePresentation method check the cryptographic integrity of the Verifiable Presentation, but it does not check if the credentialSubject.id DID matches the signer of the VP proof. The verifier is impacted by this vulnerability. Patches Patch will be available in version...
