CVE-2026-111422
Published:October 26, 2026
Updated:October 28, 2026
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.
