2.6.2rc1- Upgrade apache-airflow to this version or later
Description
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.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| apache-airflow | >= 2.5.0, < 2.6.2rc1 |
2.6.2rc1 |
| apache-airflow | >= 2.5.0, < 2.6.2 |
2.6.2 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
apache-airflow PyPI → 2.6.2rc1
- pip
pip install --upgrade "apache-airflow>=2.6.2rc1"- poetry
poetry add "apache-airflow>=2.6.2rc1"- uv
uv add "apache-airflow>=2.6.2rc1"

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
