CVE-2026-22922 Apache CVE debrief

Who should care

Defenders responsible for Apache Airflow deployments, security teams, administrators of Airflow systems, and operators managing Airflow instances should be aware of this vulnerability. These stakeholders need to assess their exposure, verify custom permissions, and implement necessary mitigations to prevent unauthorized access to task logs. Additionally, they should monitor user activity and ensure proper auditing and logging of access to sensitive areas.

Why it matters

CVE-2026-22922 is a medium-severity authorization flaw in Apache Airflow that allows authenticated users with custom permissions to view task logs without having task log access. Defenders should verify and adjust custom permissions, monitor user activity, and upgrade to Apache Airflow 3.1.7 or later.

• Potential unauthorized access to task logs
• Need to verify and adjust custom permissions for task access and task log access
• Possible impact on auditing and monitoring of authenticated user activity

Technical summary

Apache Airflow versions 3.1.0 through 3.1.6 contain an authorization flaw. An authenticated user with custom permissions limited to task access can view task logs without having task log access. This issue arises from insufficient access control checks in the task log viewing functionality. The flaw allows unauthorized access to sensitive information, potentially impacting auditing and monitoring of user activities. Upgrading to Apache Airflow 3.1.7 or later resolves this issue by implementing proper authorization checks.

Defensive priority

Upgrade to Apache Airflow 3.1.7 or later

Recommended defensive actions

• Upgrade to Apache Airflow 3.1.7 or later
• Review and adjust custom permissions for task access and task log access
• Monitor and audit authenticated user activity
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

Apache Airflow versions 3.1.0 through 3.1.6 contain an authorization flaw that can allow an authenticated user with custom permissions limited to task access to view task logs without having task log access.
