Summary

CVE-2025-65995 is a medium-severity Generation of Error Message Containing Sensitive Information (CWE-209) vulnerability in Apache Airflow. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-11 (Error Handling) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Vulnerability Data

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.

MITRE ATT&CK Enterprise TechniquesAI

T1552 Unsecured Credentials Credential Access
Adversaries may search compromised systems to find and obtain insecurely stored credentials.
Why these techniques?

Vulnerability directly exposes sensitive values/secrets in UI error tracebacks, enabling access to unsecured credentials (T1552).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires error messages to avoid revealing sensitive information that could be exploited, exactly addressing the CWE-209 exposure of operator kwargs in Airflow UI tracebacks.

prevent

Mandates filtering of sensitive data from all organizational information outputs, preventing secrets contained in DAG operator kwargs from appearing in rendered error pages.

prevent

Enforces information flow policies that can block or sanitize sensitive attributes before they reach user-facing error reporting paths.
