Recurring patterns

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

Auth Bypass: The OAuth exchange flow previously allowed authorization bypass by omitting mandatory verifiers during the access token exchange step. Developers must ensure that all OAuth token exchanges strictly validate the verifier token.

Auth Bypass: A blank-check vulnerability allowed empty strings ("") to bypass credential verification and be accepted as active credentials. Credential checks must reject blank or whitespace-only inputs explicitly.

Cleartext Transmission of Sensitive Information: The client previously defaulted to insecure transport protocols, transmitting sensitive OAuth credentials and API interactions over cleartext HTTP. Connection initializers must force HTTPS.
