CVE-2025-66017

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 CGGMP24 is missing a check in the ZK proof used in CGGMP21

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...

Missing check in ZK proof in CGGMP21 Threshold Signing Protocol

Vulnerability concerns a missing check in the ZK proof that enables an attack in which 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, we recommend upgrading to cggmp24...

Information Disclosure

github.com/bnb-chain/tss-lib is vulnerable to Information Disclosure. An attacker is able to steal the secret key shares of other participants in the signing protocol. This could happen if the attacker generates a Paillier modulus N containing small factors less than 2^100. The master key can the...

GHSA-H24C-6P6P-M3VX tss-lib leaks secret keys in response to incorrectly constructed Paillier moduli

Impact The specification of the GG18 threshold ECDSA signature protocol contains a vulnerability allowing an attacker to recover the shared secret key. If a participant generates a Paillier modulus N containing small factors less than 2^100 they can interact with other participants in the signing...
