CVE-2026-22922 is a medium-severity authorization vulnerability found in Apache Airflow versions 3.1.0 through 3.1.6. The root cause is an incorrect use of privileged APIs (CWE-648), which leads to an authorization flaw allowing authenticated users with custom permissions limited to task access to view task logs without having explicit task log access rights. This means that users who should only have limited visibility into task execution can bypass restrictions and access potentially sensitive log data. The vulnerability does not affect the integrity or availability of the system but compromises confidentiality by exposing task logs that may contain sensitive operational details, credentials, or other private information. The CVSS v3.1 score of 6.5 reflects a network attack vector with low attack complexity, requiring privileges but no user interaction, and impacting confidentiality only. The flaw was publicly disclosed on February 9, 2026, and fixed in Apache Airflow version 3.1.7. No known exploits have been reported in the wild, but the presence of this vulnerability could facilitate insider threats or lateral movement within an organization if exploited. Apache Airflow is widely used for orchestrating complex workflows and data pipelines, often in critical business environments, making the confidentiality breach significant. The vulnerability highlights the importance of correct API usage and strict permission enforcement in workflow management platforms.

For European organizations, the primary impact of CVE-2026-22922 is unauthorized disclosure of sensitive task log information. Task logs can contain detailed execution data, error messages, environment variables, and sometimes credentials or tokens used during workflow execution. Exposure of such information can lead to further attacks, including credential theft, reconnaissance, or exploitation of other vulnerabilities. Sectors heavily reliant on data pipelines and workflow automation—such as finance, telecommunications, manufacturing, and technology—may face increased risk if attackers gain access to internal operational data. The breach of confidentiality could also lead to regulatory compliance issues under GDPR if personal or sensitive data is exposed. Although the vulnerability does not affect system integrity or availability, the potential for information leakage can undermine trust and operational security. European organizations with multi-tenant or shared environments are particularly at risk if users with limited permissions can escalate visibility beyond intended boundaries.

The primary mitigation is to upgrade Apache Airflow installations to version 3.1.7 or later, where this authorization flaw is corrected. Organizations should implement a strict patch management process to ensure timely updates of workflow orchestration tools. Additionally, review and audit user permissions and roles within Airflow to enforce the principle of least privilege, ensuring users only have access necessary for their tasks. Implement monitoring and alerting on unusual access patterns to task logs, especially from users with limited permissions. Consider network segmentation and access controls to restrict Airflow UI and API access to trusted users and systems. If upgrading immediately is not feasible, temporarily restrict access to task logs or disable task log viewing features for users with custom limited permissions. Conduct regular security assessments and penetration testing focused on workflow management platforms to detect authorization weaknesses early.
