CVE-2026-111422: Apache Airflow SSH provider: SSHRemoteJobOperator: `environment` values are executed as shell on the remote host

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-26 · updated 2026-10-29
• Weakness: CWE-78

Description

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.

Affected products

• Apache Software Foundation Apache Airflow SSH provider: from 4.3.0 before 7.0.1 — fixed in 7.0.1

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Airflow SSH provider 7.0.1. Check the vendor advisory for mitigations.
