CVE-2026-41490: Dagster Vulnerable to SQL Injection via Dynamic Partition Keys in Database I/O Manager Integrations

April 18, 2026 (updated May 8, 2026)

The DuckDB, Snowflake, BigQuery, and DeltaLake I/O managers constructed SQL WHERE clauses by interpolating dynamic partition key values into queries without escaping. A user with the Add Dynamic Partitions permission could create a partition key that injects arbitrary SQL, which would execute against the target database backend under the I/O manager’s credentials.

Only deployments that use dynamic partitions are affected. Pipelines using static or time-window partitions are not impacted.
