Upgrade elliptic to version 6.5.4 or higher.
Overview
elliptic is a fast elliptic-curve cryptography implementation in plain javascript.
Affected versions of this package are vulnerable to Cryptographic Issues via the secp256k1 implementation in elliptic/ec/key.js. There is no check to confirm that the public key point passed into the derive function actually exists on the secp256k1 curve. This results in the potential for the private key used in this implementation to be revealed after a number of ECDH operations are performed.
