CVE-2024-48949

Estado: ModificadaCrítica (9.1)—

The verify function in lib/elliptic/eddsa/index.js in the Elliptic package before 6.5.6 for Node.js omits "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()" validation.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Puntuación base: 9.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.50%
Percentil entre todas las CVEs puntuadas: 41
Fecha de la puntuación: 6/10/2026

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
