CVE-2026-3118Network attack vector

Authenticated crash via embedded GraphQL fragments

Published Feb 25, 2026 · Updated Feb 25, 2026

GraphQL injection in Red Hat Developer Hub 1.8 and 1.9 allows remote authenticated users to crash and restart the platform. The Orchestrator Plugin directly embeds special characters from JSON orderBy or filter fields into backend GraphQL queries, allowing injected fragments to break query structure and raise unhandled exceptions. Any authenticated user can trigger the platform-wide restart remotely without user interaction, temporarily interrupting access for all legitimate users.
