CISA KEV Advisory
Apache Airflow's Experimental API Authentication Bypass
The previous default setting for Airflow's Experimental API was to allow all API requests without authentication.
Apply updates per vendor instructions.
Risk Analysis
Apache Airflow's Experimental API previously allowed all API requests without authentication by default. This high-severity misconfiguration, with an EPSS score of 0.94186 and active exploitation, presents a significant risk of unauthorized access.
This vulnerability is actively exploited in the wild. The lack of default authentication allowed remote, unauthenticated access to the API.
Ensure that authentication is properly configured and enabled for Apache Airflow's Experimental API. Review and update Airflow configurations to enforce strong authentication policies.
Technical Analysis
CVE-2020-13927 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2020-13927 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
