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.","state":0,"publishedAt":"2025-11-25T20:16:00.64+00:00","modifiedAt":"2026-10-18T20:10:00.11+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.3,"severity":"CRITICAL"}],"references":["https://github.com/LFDT-Lockness/cggmp21/security/advisories/GHSA-m95p-425x-x889","https://www.dfns.co/article/cggmp21-vulnerabilities-patched-and-explained"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66016","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-345"],"productCriteria":[],"sourceDates":{"published":"2025-11-25T20:16:00.640","lastModified":"2026-10-18T20:10:00.110"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
