Unauthenticated service interruption via repeated GraphQL directives
Published Jan 19, 2026 · Updated Jan 19, 2026
Denial of service in Birkir Gudjonsson Prime 0.4.0.beta allows remote attackers to interrupt service via crafted GraphQL requests. The /graphql directive handler executes processing logic for every repeated directive at the same location, allowing one query to exhaust computing resources. No authentication or user interaction is required, and the documented consequence is resource exhaustion without data disclosure or modification.
