Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: SASL login failure could fall back to non-SASL methods, bypassing authentication. Fix added isAuthenticated() check after SASL login.
Auth Bypass: SASL authentication was considered successful without verifying server response code 235, allowing spoofed success.
Privilege Escalation: File access for configuration loading was not wrapped in doPrivileged, allowing unauthorized access to privileged resources.
