How to Fix CVE-2023-35005

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.

apache-airflow fixed: 2.6.2rc1 
pip install apache-airflow>=2.6.2rc1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show apache-airflow

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-35005, inspect your installed packages using pip:

pip show apache-airflow

Analyze 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 2.6.2rc1), your application is affected.

Note: The pip show apache-airflow command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Apache airflow, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In Apache Airflow, some potentially sensitive values were being shown to the user in certain situations. This vulnerability is mitigated by the fact configuration is not shown in the UI by default (only if `[webserver] expose_config` is set to `non-sensitive-only`), and not all uncensored values are actually sentitive. This issue affects Apache Airflow: from 2.5.0 before 2.6.2. Users are recommended to update to version 2.6.2 or later.
