📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could execute arbitrary commands, access sensitive Google Cloud data, or manipulate cloud resources through parameter injection.
Likely Case
Unauthorized data access or manipulation in connected Google Cloud services, potentially leading to data breaches or service disruption.
If Mitigated
Limited impact with proper network segmentation and minimal permissions, potentially only affecting non-critical data.
🎯 Exploit Status
Exploitation requires access to Airflow interface or API and knowledge of Google Cloud integration.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.10.0 and later
Vendor Advisory: https://lists.apache.org/thread/ks4l78l5rwdpmvfn7y7yhs179nyxtlsh
Restart Required: Yes
Instructions:
1. Update Apache Airflow Google Provider to version 8.10.0 or later using pip: pip install --upgrade apache-airflow-providers-google>=8.10.0
2. Restart all Airflow services (webserver, scheduler, workers)
3. Verify the update with: pip show apache-airflow-providers-google
🔧 Temporary Workarounds
Restrict Airflow Access
allLimit network access to Airflow instances to trusted IPs only
Configure firewall rules to restrict access to Airflow ports (typically 8080)
Minimize Google Cloud Permissions
allApply principle of least privilege to Google Cloud service accounts
Review and restrict IAM permissions for Airflow service accounts in GCP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Airflow instances
- Apply additional authentication/authorization layers before Airflow access
