CVE-2025-67895 is a critical vulnerability classified under CWE-669 (Incorrect Resource Transfer Between Spheres) affecting the Apache Airflow Providers Edge3 integration when deployed on Apache Airflow version 2. The Edge3 provider prior to version 2.0.0 was intended only for development and testing purposes and was never officially released for production use on Airflow 2. However, if installed and configured on Airflow 2, it implicitly enabled a non-public API that was designed for internal testing. This API allows DAG authors—users who define Directed Acyclic Graphs for workflow orchestration—to perform remote code execution (RCE) within the webserver context. This is a significant breach of the intended security model, as DAG authors should not have the capability to execute arbitrary code on the server hosting Airflow. The vulnerability does not affect Airflow 3 or Edge3 provider versions 2.0.0 and later, as these versions remove the vulnerable code and require Airflow 3 as a minimum version. The CVSS v3.1 score of 9.8 indicates that the vulnerability is remotely exploitable without authentication or user interaction, with a high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, but the severity and ease of exploitation make it a critical threat. The recommended remediation is to uninstall the Edge3 provider from Airflow 2 and migrate to Airflow 3 with the updated Edge3 provider version 2.0.0 or later, which eliminates the vulnerable code paths.

The impact of CVE-2025-67895 on European organizations can be severe, especially for those relying on Apache Airflow 2 with the Edge3 provider for workflow automation and data pipeline orchestration. Successful exploitation allows an attacker with DAG author privileges to execute arbitrary code on the Airflow webserver, potentially leading to full system compromise, data exfiltration, disruption of critical workflows, and lateral movement within the network. This can affect confidentiality by exposing sensitive data processed by Airflow, integrity by altering workflows or injecting malicious tasks, and availability by disrupting or halting automated processes. Given that Airflow is widely used in industries such as finance, telecommunications, manufacturing, and public sector organizations across Europe, the vulnerability poses a significant risk to operational continuity and data security. The lack of authentication or user interaction requirements for exploitation increases the threat level, making it easier for malicious insiders or compromised accounts to leverage this flaw. Additionally, the vulnerability could be exploited to deploy ransomware or other malware, amplifying the potential damage. Organizations that have not upgraded to Airflow 3 or removed the vulnerable Edge3 provider are at heightened risk.

To mitigate CVE-2025-67895, European organizations should take immediate and specific actions beyond generic patching advice: 1) Identify all instances of Apache Airflow 2 deployments with the Edge3 provider installed. 2) Uninstall the Edge3 provider from Airflow 2 environments as it contains the vulnerable non-public API. 3) Plan and execute a migration to Apache Airflow 3, ensuring that the Edge3 provider version is upgraded to 2.0.0 or later, which removes the vulnerable code. 4) Restrict DAG author privileges to trusted personnel only, minimizing the risk of insider exploitation. 5) Implement network segmentation and access controls to limit exposure of the Airflow webserver to untrusted networks. 6) Monitor Airflow logs and system behavior for unusual activity indicative of exploitation attempts. 7) Conduct security audits and code reviews of DAGs to detect potentially malicious or unauthorized code. 8) Stay updated with Apache Airflow security advisories and apply future patches promptly. These targeted steps will reduce the attack surface and prevent exploitation of this critical vulnerability.
