3.1.6- Upgrade apache-airflow to this version or later
Description
In Apache Airflow versions before 3.1.6, and 2.11.1 the proxies and proxy fields within a Connection may include proxy URLs containing embedded authentication information. These fields were not treated as sensitive by default and therefore were not automatically masked in log output. As a result, when such connections are rendered or printed to logs, proxy credentials embedded in these fields could be exposed.
Users are recommended to upgrade to 3.1.6 or later for Airflow 3, and 2.11.1 or later for Airflow 2 which fixes this issue.

2.11.1 |
| apache-airflow | < 3.1.6 |
3.1.6 |
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 → 3.1.6

Weakness
CWE-532: Insertion of Sensitive Information into Log File
The product writes sensitive information to a log file.
How to prevent it
- Architecture and Design, Implementation: Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
- Distribution: Remove debug log files before deploying the application into production.
- Operation: Protect log files against unauthorized read/write.
- Implementation: Adjust configurations appropriately when software is transitioned from a debug state to production.
