CVE-2023-42319Public exploitNetwork attack vector

Unauthenticated service hang via GraphQL alias flooding

Published Oct 18, 2023 · Updated Sep 13, 2024

Denial of service in Ethereum Foundation go-ethereum through 1.13.4 allows remote attackers to hang the node via its GraphQL endpoint. The GraphQL handler executes unlimited aliased operations in one HTTP request, repeatedly evaluating expensive log queries and consuming large amounts of memory. The endpoint must be enabled with --http --graphql and reachable by the attacker; exploitation interrupts node service without providing data or code execution.
