High risk

Summary

The ethereum/go-ethereum repository exhibits high quantum vulnerability due to extensive reliance on secp256k1 elliptic curve cryptography and ECDH key exchange mechanisms. These cryptographic primitives will be completely broken by quantum computers running Shor's algorithm, threatening the entire Ethereum blockchain's security model. Immediate planning for post-quantum migration is critical for long-term viability.
