CVE-2024-48949
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.

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. This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.
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.
