Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Using inactive broker configurations during TLS connection establishment can cause the client to extract incorrect Common Names (CNs) for server name verification, potentially allowing unauthorized or stale brokers to bypass validation checks.

Insecure TLS Validation: Failing to honor the user-configured broker TLS root certification authority (CA) pool exposes the client to Man-in-the-Middle (MITM) attacks by falling back to potentially insecure default trust stores or failing validation entirely.
