Recurring patterns

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

Authentication Bypass: Multiple fixes addressed insecure password comparison, including plaintext equality and weak hashing, indicating a persistent vulnerability in the GUI authentication path.

Weak Password Hashing: Password hashing was upgraded to argon2id, but a prior fix used only SHA-256 pre-hashing, showing evolution toward stronger hashing but with historical weakness.

Configuration Injection: An environment variable (APP_SEEDLIST) allowed arbitrary archiver IP injection; the fix hardcoded trusted IPs, showing a need to eliminate untrusted configuration sources.
