The revocation schema 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, allowing a malicious holder of a revoked credential to generate a valid Non-Revocation Proof for that credential as part of an AnonCreds presentation. A verifier may verify a credential from a holder as being &#34;not revoked&#34; when in fact, the holder&#39;s credential has been revoked. Ursa has moved to end-of-life status and no fix is expected.</p> <p><strong>Affected:</strong> hyperledger-archives ursa, hyperledger ursa</p> <p>Ursa is a cryptographic library for use with blockchains.
