How to Fix CVE-2021-28359
To remediate this vulnerability, upgrade all affected Apache airflow dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install apache-airflow>=1.10.15pip install apache-airflow>=2.0.2Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show apache-airflowHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2021-28359, inspect your installed packages using pip:
pip show apache-airflowAnalyze the terminal output to locate any version of Apache airflow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.15), your application is affected.
Note: The pip show apache-airflow command checks currently installed packages in your active Python environment.
