A critical security flaw has emerged in Apache Airflow 3.0.3, exposing sensitive connection information to users with only read permissions.<\/p>\n
The vulnerability, tracked as CVE-2025-54831 and classified as \u201cimportant\u201d severity, fundamentally undermines the platform\u2019s intended security model for handling sensitive data<\/a> within workflow connections.<\/p>\n Apache Airflow version 3.0 introduced significant changes to how sensitive information in connections is managed, implementing a \u201cwrite-only\u201d model designed to restrict access to sensitive connection fields exclusively to Connection Editing Users.<\/p>\n This security enhancement was intended to prevent unauthorized access to critical authentication details, database credentials, and API keys stored within Airflow connections.<\/p>\n However, the implementation in version 3.0.3 contained a critical flaw that reversed these security improvements.<\/p>\n The vulnerability allows users with standard READ permissions to access sensitive connection information through both the Airflow API and web user interface.<\/p>\n This exposure occurs regardless of the The breach effectively renders the security configuration ineffective, creating a significant risk for organizations relying on Airflow\u2019s access controls.<\/p>\n Apache security analysts identified<\/a> the vulnerability after observing unexpected behavior in connection handling mechanisms.<\/p>\n The flaw specifically affects Apache Airflow<\/a> version 3.0.3, while earlier Airflow 2.x versions remain unaffected since they follow different connection handling protocols where exposing sensitive information to connection editors was the documented behavior.<\/p>\n The vulnerability stems from improper implementation of the connection access control system introduced in Airflow 3.0.<\/p>\n When users with READ permissions query connection details via the Organizations using Apache<\/a> Airflow 3.0.3 should immediately upgrade to version 3.0.4 or later to address this security vulnerability and restore proper access controls for sensitive connection information.<\/p>\n Follow us on\u00a0Google News<\/a>,\u00a0LinkedIn<\/a>,\u00a0and\u00a0X<\/a>\u00a0to Get More Instant Updates<\/strong>,\u00a0Set CSN as a Preferred Source in\u00a0Google<\/a>.<\/strong><\/p>\n The post Apache Airflow Vulnerability Exposes Sensitive Details to Read-Only Users<\/a> appeared first on Cyber Security News<\/a>.<\/p>\n<\/div>\nAIRFLOW__CORE__HIDE_SENSITIVE_VAR_CONN_FIELDS<\/code> configuration setting, which is specifically designed to mask sensitive connection details from unauthorized users.<\/p>\nConnection Access Control Mechanism<\/strong><\/h2>\n
