Signature Malleabillity in elliptic
Quick fix
GHSA-vh7m-p724-62c2 — elliptic: upgrade to the fixed version with the command below.
npm install elliptic@6.5.3Details
The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.
