📦 What is this software?
Lunary by Lunary
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all project data including sensitive information, unauthorized data manipulation, and potential data destruction across all projects in the organization.
Likely Case
Unauthorized access to project resources leading to data exposure, privilege escalation, and potential data manipulation by authenticated but unauthorized users.
If Mitigated
Limited to authenticated users within the organization, but proper authorization prevents cross-project access and manipulation.
🎯 Exploit Status
Exploitation requires authenticated access but minimal technical skill to manipulate project access requests.

🔧 Temporary Workarounds
Temporary access restriction
allImplement network-level restrictions to limit access to project management endpoints
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to lunary instances
- Enable detailed audit logging for all project access attempts and monitor for unauthorized access patterns
🔍 How to Verify
Check if Vulnerable:
Check if running lunary-ai/lunary version v1.2.13 by examining package version or commit hashCheck Version:
Check package.json or git log for version/commit informationVerify Fix Applied:
Test project access controls by attempting to access projects with users who shouldn't have permissions📡 Detection & Monitoring
Log Indicators:
- Unauthorized project access attempts
- Multiple project access requests from single user across different projects
- Failed authorization checks in middleware logs
Network Indicators:
- Unusual patterns of API calls to project endpoints
- Multiple project ID requests from single user session
SIEM Query:
search 'project_access' OR 'authorization_failed' OR 'unauthorized_project' in application logs
