CVE-2026-30898Network attack vector

Command execution via unescaped dag_run.conf templating

Published Apr 18, 2026 · Updated Apr 18, 2026

Command injection in Apache Airflow before 3.2.0 allows remote authenticated users to execute code on workers through crafted Dag run configuration. Affected DAGs interpolate dag_run.conf values directly into a BashOperator bash_command, where Jinja rendering inserts unescaped input into the shell command. Exploitation requires UI access to submit configuration for a DAG that adopted the unsafe documentation example, and execution occurs with the worker task's privileges.
