CVE-2023-42319: go-ethereum vulnerable to denial of service via crafted GraphQL query

October 18, 2023 (updated September 13, 2024)

Geth (aka go-ethereum) through 1.13.4, when --http --graphql is used, allows remote attackers to cause a denial of service (memory consumption and daemon hang) via a crafted GraphQL query.

NOTE: the vendor’s position is that the “graphql endpoint [is not] designed to withstand attacks by hostile clients, nor handle huge amounts of clients/traffic.
