CVE-2024-45784: Apache Airflow: Sensitive configuration values are not masked in the logs by default

Severity: high (CVSS 7.5 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 1.3% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2024-11-15 · updated 2026-06-17
Weakness: CWE-1295

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.

Affected products

Apache Airflow: before 2.10.3 — fixed in 2.10.3

How to fix

Upgrade to a fixed version: Apache Airflow 2.10.3. Check the vendor advisory for mitigations.
