CVE-2024-22192 (GCVE-0-2024-22192)

Vulnerability from cvelistv5 – Published: 2024-01-16 21:44 – Updated: 2025-06-16 19:46

Title

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

Summary

Ursa is a cryptographic library for use with blockchains. 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 verifiable presentation that includes a Non-Revocation proof. The impact of the flaw is that a malicious verifier may be able to determine a unique identifier for a holder presenting a Non-Revocation proof. Ursa has moved to end-of-life status and no fix is expected.

Severity
