cggmp24 and cggmp21 are vulnerable to signature forgery through altered presignatures

Impact This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously users could generate a presignature, and then choose a HD derivation path while issuing a partial signature via...

cggmp21 has a missing check in the ZK proof used in CGGMP21

Impact cggmp21 concerns a missing check in the ZK proof that enables an attack in which a single malicious signer can reconstruct full private key. Patches cggmp21 v0.6.3 is a patch release that contains a fix that introduces this specific missing check However, cggmp21 recommends upgrading to...

CVE-2025-66016

CGGMP24 (ECDSA TSS) CVE-2025-66016 concerns a missing check in the ZK proof in CGGMP21 that could allow a single malicious signer to reconstruct the full private key. The issue is described across multiple sources: prior to version 0.6.3, the missing check enabled the attack; a patch exists in v0...

CVE-2025-66017: Use of a Broken or Risky Cryptographic Algorithm

CGGMP24 is a state-of-art ECDSA TSS protocol that supports 1-round signing requires 3 preprocessing rounds, identifiable abort, and a key refresh protocol. In versions 0.6.3 and prior of cggmp21 and version 0.7.0-alpha.1 of cggmp24, presignatures can be used in the way that significantly reduces...

CVE-2025-66016: Insufficient Verification of Data Authenticity

CGGMP24 is a state-of-art ECDSA TSS protocol that supports 1-round signing requires 3 preprocessing rounds, identifiable abort, and a key refresh protocol. Prior to version 0.6.3, there is a missing check in the ZK proof that enables an attack in which single malicious signer can reconstruct full...
