{"id":"CVE-2024-48949","aliases":["GHSA-434g-2637-qmqr"],"url":"https://o3.security/vulnerability/CVE-2024-48949","summary":"Elliptic's verify function omits uniqueness validation","details":"The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proof(s) is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the `verify` function in `lib/elliptic/eddsa/index.js` omits `sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()` validation.\n\nThis vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.","published":"2024-10-10T00:00:00Z","modified":"2026-08-12T03:51:46.834871930Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.00496,"percentile":0.40219,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"elliptic","fixedVersion":"6.5.6"}],"fix":{"url":"https://github.com/indutny/elliptic/commit/7ac5360118f74eb02da73bdf9f24fd0c72ff5281","label":"indutny/elliptic@7ac5360"},"references":[{"type":"WEB","url":"https://github.com/indutny/elliptic/compare/v6.5.5...v6.5.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/48xxx/CVE-2024-48949.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-48949"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20241227-0003/"},{"type":"FIX","url":"https://github.com/indutny/elliptic/commit/7ac5360118f74eb02da73bdf9f24fd0c72ff5281"},{"type":"ARTICLE","url":"https://blog.trailofbits.com/2025/11/18/we-found-cryptography-bugs-in-the-elliptic-library-using-wycheproof/"},{"type":"WEB","url":"https://blog.trailofbits.com/2025/11/18/we-found-cryptography-bugs-in-the-elliptic-library-using-wycheproof"},{"type":"PACKAGE","url":"https://github.com/indutny/elliptic"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20241227-0003"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.834871930Z"}}
