Vulnerability from github – Published: 2026-10-27 00:32 – Updated: 2026-10-27 03:32

Details

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.

CVE-2026-111422 (GCVE-0-2026-111422)

Vulnerability from cvelistv5 – Published: 2026-10-26 23:29 – Updated: 2026-10-27 00:17

Title

Apache Airflow SSH provider: SSHRemoteJobOperator: `environment` values are executed as shell on the remote host

Summary

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.
