CVE-2025-65995: Apache Airflow: Disclosure of secrets to UI via kwargs

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.9% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-02-21 · updated 2026-06-17
• Weakness: CWE-209

Description

When a DAG failed during parsing, Airflow’s error-reporting in the UI could include the full kwargs passed to the operators. If those kwargs contained sensitive values (such as secrets), they might be exposed in the UI tracebacks to authenticated users who had permission to view that DAG.  The issue has been fixed in Airflow 3.1.4 and 2.11.1, and users are strongly advised to upgrade to prevent potential disclosure of sensitive information.

Affected products

• Apache Airflow: before 2.11.1; from 3.0.0 before 3.1.4 — fixed in 2.11.1, 3.1.4

How to fix

Upgrade to a fixed version: Apache Airflow 2.11.1, 3.1.4. Check the vendor advisory for mitigations.
