RCE in Apache Airflow example_xcom DAG pattern
CVE-2025-54550 is a low-severity arbitrary code execution issue associated with the example_xcom DAG pattern documented for Apache Airflow. The documented example read values from XCom using an unsafe pattern that, under a race-condition scenario, could be abused by a UI user who had permission to modify XCom entries. By altering XCom data before it was consumed by the worker, the attacker could cause attacker-controlled content to be processed in a way that resulted in arbitrary code execution on the worker. Apache stated that the Airflow release itself was not directly affected because example_dags are not intended to be enabled in production, but users who copied or implemented the documented pattern in their own DAGs could reproduce the vulnerability. Documentation for Airflow 3.2.0 includes a more resilient version of the example.
