CVE-2025-66016
No affected components available
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 private key. This issue has been patched in version 0.6.3, for full mitigation it is recommended to upgrade to cggmp24 version 0.7.0-alpha.2 as it contains more security checks.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability.
