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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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","score":9.3,"severity":null}],"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://euvd.enisa.europa.eu/vulnerability/EUVD-2025-199643","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Nov 25, 2025, 7:48:16 PM","dateUpdated":"Nov 25, 2025, 8:57:34 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
