⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining root/admin privileges and persistent access to the host running Debezium UI.
Likely Case
Local attacker gains elevated privileges to access sensitive data, modify configurations, or disrupt Debezium operations.
If Mitigated
Limited impact with proper access controls and isolation preventing local users from accessing the Debezium UI interface.
🎯 Exploit Status
Exploit requires local access to the Debezium UI interface. Public proof-of-concept demonstrates credential disclosure leading to code execution.
