CVE-2026-68969 Apache Software Foundation CVE debrief
Apache Airflow's audit log contained cleartext Variable values and Connection `extra` contents when submitted through bulk endpoints. Authenticated users with audit-log read access could recover secrets verbatim. The Airflow UI's Import Variables action also wrote secrets to the log. This vulnerability allows unauthorized access to sensitive information. Users should upgrade to apache-airflow 3.3.1 or later to prevent this exposure. The vulnerability is particularly concerning for defenders responsible for Apache Airflow deployments with sensitive information stored in Variables or Connections.

Who should care
Defenders responsible for Apache Airflow deployments, particularly those with sensitive information stored in Variables or Connections, should assess their exposure and prioritize upgrading to apache-airflow 3.3.1 or later.
Why it matters
CVE-2026-68969 allows authenticated users with audit-log read access to recover sensitive information, including Variable values and Connection `extra` contents, due to cleartext logging in Apache Airflow's audit log. Defenders should prioritize upgrading to apache-airflow 3.3.1 or later.
- Recovery of sensitive information by authenticated users with audit-log read access
- Potential exposure of secrets in audit logs
- Need for upgrade to apache-airflow 3.3.1 or later to prevent unauthorized access
Technical summary
Apache Airflow wrote Variable values and Connection `extra` contents to the audit log in cleartext when submitted through bulk endpoints. The audit-log masking did not apply to nested entities, allowing authenticated users with audit-log read access to recover secrets verbatim. This vulnerability is particularly concerning for defenders responsible for Apache Airflow deployments with sensitive information stored in Variables or Connections. The vulnerability allows unauthorized access to sensitive information, and users should upgrade to apache-airflow 3.3.1 or later to prevent this exposure.
Defensive priority
Defenders should prioritize upgrading to apache-airflow 3.3.1 or later to prevent unauthorized access to sensitive information. They should also review their audit logs for potential exposure of secrets.
Recommended defensive actions
- Upgrade to apache-airflow 3.3.1 or later
- Review audit logs for potential exposure of secrets
- Restrict access to audit logs to authorized personnel
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
Evidence notes
The CVE record and NVD entry provide details on the vulnerability, including its description, CVSS score, and affected versions. The Apache Airflow project has released a patch for the issue. The vulnerability was introduced due to the audit-log masking not applying to nested entities in bulk requests. This allowed authenticated users with audit-log read access to recover sensitive information verbatim. The Airflow UI's Import Variables action also wrote secrets to the log, further increasing the risk of exposure. Defenders should be
