CVE-2024-1643
📋 TL;DR
This vulnerability allows attackers to join any organization by knowing its ID, bypassing permission checks. Once joined, they gain full read/write access to all organization data. This affects all Lunary users with vulnerable versions deployed.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all organizational data including sensitive information, intellectual property, and user data, leading to data theft, destruction, or ransomware deployment.
Likely Case
Unauthorized access to sensitive organizational data, potential data exfiltration, and unauthorized modifications to critical information.
If Mitigated
Limited impact with proper network segmentation and monitoring, but still represents a significant authentication bypass vulnerability.
🎯 Exploit Status
Exploitation requires only knowledge of an organization ID, which could be obtained through enumeration or information disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.2.2
Vendor Advisory: https://github.com/lunary-ai/lunary/commit/67eaefe1c77c882c628780940c704a117b561d51
Restart Required: Yes
Instructions:
1. Update Lunary to version 1.2.2 or later. 2. Restart the application. 3. Verify the fix by testing organization join functionality.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to Lunary instances to only trusted users and networks.
Rate Limiting
allImplement rate limiting on organization join endpoints to prevent brute-force enumeration.
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the Lunary application
- Deploy additional authentication layers (API gateway, WAF) that validate organization membership before requests reach Lunary
🔍 How to Verify
Check if Vulnerable:
Check if your Lunary version is below 1.2.2. Attempt to join an organization without proper permissions using only the organization ID.Check Version:
Check the Lunary application version in the admin interface or deployment configuration.Verify Fix Applied:
After updating to 1.2.2+, verify that organization join requests now properly validate user permissions and reject unauthorized attempts.📡 Detection & Monitoring
Log Indicators:
- Unusual organization join events
- Multiple failed permission checks followed by successful organization access
- User accounts accessing organizations they shouldn't have access to
Network Indicators:
- Unusual patterns of organization ID enumeration requests
- Spikes in organization join API calls
