Recurring patterns

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

Insecure Deserialization: Unserializing base64-decoded network messages without an allowlist enables object injection and potential RCE; this is the highest-impact risk and must be guarded on every message-handling path.

Reflected XSS: Reflecting request method/URI into HTML without htmlspecialchars allows script injection in any browser-rendered dump; any HTML-rendering path must escape context.

Terminal Escape Sequence Injection: Unescaped control characters in CLI output can manipulate terminal sessions; any CLI-rendering path must strip or escape ANSI/control sequences.
