🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor was contacted but did not respond. Consider upgrading to any version beyond 2.21.10 if available.
🔧 Temporary Workarounds
Restrict access to /actuator endpoint
allBlock or restrict access to the vulnerable /actuator endpoint using web server configuration or firewall rules
# Example for nginx: location /actuator { deny all; }
# Example for Apache: <Location /actuator> Require all denied </Location>
Network segmentation
allIsolate Halo instances from untrusted networks and restrict access to management interfaces
# Use firewall rules to restrict access to Halo ports from trusted IPs only
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the Halo instance
- Monitor access logs for suspicious requests to the /actuator endpoint
🔍 How to Verify
Check if Vulnerable:
Check if Halo version is 2.21.10 or earlier and if /actuator endpoint is accessibleCheck Version:
Check Halo version in application settings or via application metadataVerify Fix Applied:
Verify that /actuator endpoint returns 403/404 or is inaccessible after applying workarounds📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /actuator endpoint from unusual sources
- Multiple failed access attempts to management endpoints
