Authenticated code execution via example DAG shell interpolation
Published Aug 16, 2022 · Updated Aug 3, 2024
Command injection in Apache Airflow Docker Provider before 3.0.0 allows remote authenticated users to execute code on worker hosts. The shipped docker_sample_copy_data DAG inserts templated source paths and a prior task's filename output into commands executed through BashOperator and /bin/bash -c without shell-safe quoting. Exploitation requires the example DAG to be loaded and an authenticated user to influence its inputs; successful commands run with the worker's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
