Live demo breaks a Laravel app end-to-end: crowdsourced brute force shows IP rate limits are trivial to bypass, a signed verification URL is accepted when the signature check was left for backward compatibility, an IDOR to admin (id=13) lets attackers edit the admin bio, CommonMark rendering enables a CommonMark XSS in admin bio that runs JS in the admin browser to escalate roles, and an encoded path traversal lets attackers read .env via encoded path traversal to steal APP_KEY and decrypt session cookies for full site takeover — the demo works live.
