CVE-2026-41490Network attack vector

Authenticated SQL injection via unescaped partition keys

Published May 7, 2026 · Updated May 7, 2026

SQL injection in Dagster before 1.13.1 and its I/O libraries before 0.29.1 allows remote authenticated users to read or modify database data. DuckDB, Snowflake, BigQuery, and DeltaLake I/O managers interpolate dynamic partition keys into SQL WHERE clauses without escaping them, so injected SQL runs under the manager's database credentials. Exploitation requires API access and dynamic-partition creation rights; static and time-window partition deployments are unaffected.
