CVE-2024-48949

Summary

CVE-2024-48949 is a vulnerability affecting the Elliptic package before version 6.5.6 in Node.js. The issue lies within the verify function in lib/elliptic/eddsa/index.js file. This flaw permits an attacker to bypass signature verification checks by providing an invalid signature, as the necessary validation for the signature's S value, including "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()," is omitted. Consequently, this vulnerability can lead to data integrity issues and unauthorized access to sensitive data. It is crucial for Node.js users to update to the latest version of Elliptic to mitigate this risk.
