Description
Apache Airflow versions before 2.10.3 contain a vulnerability that could expose sensitive configuration variables in task logs. This vulnerability allows DAG authors to unintentionally or intentionally log sensitive configuration variables. Unauthorized users could access these logs, potentially exposing critical data that could be exploited to compromise the security of the Airflow deployment. In version 2.10.3, secrets are now masked in task logs to prevent sensitive configuration variables from being exposed in the logging output. Users should upgrade to Airflow 2.10.3 or the latest version to eliminate this vulnerability. If you suspect that DAG authors could have logged the secret values to the logs and that your logs are not additionally protected, it is also recommended that you update those secrets.

| Package | Vulnerable | Fixed in |
|---|---|---|
| airflow | < 2.10.3 |
2.10.3 |
| apache-airflow | < 2.10.3 |
2.10.3 |
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.
airflow PyPI → 2.10.3
- pip
pip install --upgrade "airflow>=2.10.3"- poetry
poetry add "airflow>=2.10.3"- uv
uv add "airflow>=2.10.3"

Weakness
CWE-1295: Debug Messages Revealing Unnecessary Information
The product fails to adequately prevent the revealing of unnecessary and potentially sensitive system information within debugging messages.
How to prevent it
- Implementation: Ensure that a debug message does not reveal any unnecessary information during the debug process for the intended response.
