CVE-2026-68971 Apache CVE debrief

Who should care

Airflow administrators and security teams responsible for deployments using multi-team mode with team-aware auth managers should assess exposure and take remediation steps. This includes reviewing authorization configurations, upgrading to apache-airflow 3.3.1 or later, and monitoring for suspicious activity. Security teams should also verify affected versions and deployment configurations to ensure proper mitigation.

Why it matters

CVE-2026-68971 allows unauthorized access to Dag runs and XCom values in Apache Airflow deployments using multi-team mode with team-aware auth managers. Defenders should assess exposure, upgrade to apache-airflow 3.3.1 or later, and review authorization configurations.

• Authenticated users in one team could trigger Dag runs belonging to another team
• Authenticated users in one team could read XCom values from another team
• Requires verification of affected versions and deployment configurations
• Remediation priority for deployments using multi-team mode with team-aware auth managers

Technical summary

Apache Airflow's asset materialization endpoint and XCom result check did not properly authorize target Dags based on team. This allowed authenticated users in one team to trigger Dag runs and read XCom values from another team in deployments using multi-team mode with team-aware auth managers. The issue is resolved in apache-airflow 3.3.1 or later. Affected deployments should be upgraded and authorization configurations reviewed. The vulnerability does not affect deployments using the FAB auth manager due to its single-team support.

Defensive priority

Airflow administrators and security teams should assess exposure and upgrade to apache-airflow 3.3.1 or later.

Recommended defensive actions

• Upgrade to apache-airflow 3.3.1 or later
• Review and update authorization configurations for team-aware auth managers
• Monitor for suspicious activity on Dag runs and XCom values
• 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

The CVE record and NVD entry provide details on the vulnerability in Apache Airflow's asset materialization endpoint and XCom result check. Evidence is limited to public CVE and NVD records. Defenders should verify affected versions and deployment configurations, focusing on multi-team mode with team-aware auth managers. The CVE Program and NVD detail pages offer official guidance.
