What is CVE-2026-41490?

Dagster, an orchestration platform for managing data assets, has a vulnerability in its handling of dynamic partition keys. In versions prior to 1.13.1 for Dagster Core and 0.29.1 for its libraries, the system allowed the construction of SQL WHERE clauses that lacked proper escaping. This flaw enables users with the Add Dynamic Partitions permission to inject arbitrary SQL code that would execute against the connected database using the I/O manager's credentials. Only instances utilizing dynamic partitions are at risk; those using static or time-window partitions remain unaffected. A resolution has been implemented in the latest versions.
