The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The use of symmetric AES encryption for client credential delivery allowed potential interception and decryption of sensitive sync credentials, which was resolved by upgrading to asymmetric RSA encryption.
Auth Bypass: A lack of strict IP-based rate limiting and ban blocks on authentication failures allowed brute-force attacks against the sync server authentication flow.
