CVE-2026-111422
Apache Airflow SSH provider: SSHRemoteJobOperator: `environment` values are executed as shell on the remote host
In apache-airflow-providers-ssh before 7.0.1, SSHRemoteJobOperator quoted the values of its templated environment parameter only once, although they are placed inside an already-quoted wrapper script, so shell syntax such as $(...) in a value was executed on the remote SSH host. In a Dag that passes trigger-time input such as params or dag_run.conf into environment, a user who can trigger that Dag but cannot author Dags could run arbitrary commands on the remote host as the SSH connection's user. Users are advised to upgrade apache-airflow-providers-ssh to 7.0.1 or later.
