CVE-2025-0453Public exploitNetwork attack vector

Service interruption via unbounded batched GraphQL queries

Published Mar 20, 2025 · Updated Oct 15, 2025

Uncontrolled resource consumption in MLflow 2.17.2 allows remote attackers to interrupt service through batched GraphQL queries. The /graphql endpoint accepts large query batches that repeatedly enumerate every run in an experiment without bounding work per request. No authentication or user interaction is required, but exploitation depends on sufficiently expensive queries occupying all available workers.
