AI-suggested
Deployments should upgrade to Apache Airflow version 3.4.0 or later to fully address CVE-2026-96285. The partial fix in version 3.3.1 is insufficient and does not prevent constructor execution during deserialization. No other mitigations or configuration changes are indicated.
Description
Apache Airflow versions before 3.3.0 are not affected by CVE-2026-96285. Version 3.3.1 includes a partial fix that checks the scheduler's decoded next_kwargs value is a dictionary only after deserializing the entire stored payload. This deserialization process reconstructs nested objects and runs their constructors before the check, allowing a DAG author to trigger constructor execution in the scheduler and API server without non-default configuration. The fix in 3.3.1 is incomplete; deployments must upgrade to version 3.4.0 or later for a complete resolution.
