Upgrade apache-airflow-providers-ssh to version 7.0.1 or higher.
Overview
apache-airflow-providers-ssh is a Provider package apache-airflow-providers-ssh for Apache Airflow
Affected versions of this package are vulnerable to Command Injection via the build_posix_wrapper_command function in remote_job.py, where environment variable values passed to SSHRemoteJobOperator are not properly quoted before being spliced into a single-quoted shell script literal. An attacker who controls an environment variable value containing shell metacharacters (such as $(...), backticks, or ;) can cause those characters to be interpreted by the remote wrapper shell rather than passed as literal strings to the job, enabling arbitrary command execution on the remote host. The root cause is that the per-value escaping used only a single level of single-quote escaping, which was insufficient because the export block was then embedded inside another single-quoted literal without a second escaping pass.
