3 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
TLS Hostname Verification: Two separate fixes were needed to add hostname verification, indicating the initial implementation lacked it entirely and later required refinement to use SAN or CN correctly.
Insecure TLS Configuration / Auth Bypass: The login flow originally did not enforce SSL or certificate verification, allowing MITM downgrade or certificate bypass. The fix introduced SSLMode to control requireSsl/startSsl/verifyCertificate.
