Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Broken Cryptography: Incomplete error handling during SSL post-connection hostname verification allowed socket connections to remain open despite verification failures. This presents a high risk of active man-in-the-middle attacks where invalid certificates are silently tolerated.
Broken Cryptography: TLS certificate verification was historically disabled by default when initializing SSL contexts, requiring explicit opt-in and exposing default configurations to passive or active interception.
Insecure Defaults: The library defaulted to plaintext SMTP connections instead of opportunistically upgrading to STARTTLS when supported by the server, exposing email payloads to surveillance.
