Ethers < 5.0.30 used Elliptic.js 6.5.3 which did not check to ensure that the public key passed in to ECDH is a point that actually exists on the curve. This opens up for a twist attack which could be used to reveal the private key of a party in an ECDH operation over a number of occurances. ethers-io/ethers.js#1284 https://github.com/christianlundkvist/blog/blob/master/2020_05_26_secp256k1_twist_attacks/secp256k1_twist_attacks.md CVE: CVE-2020-28498
