Browser devtools + curl reveal a JWT sent to the app; copying that token and posting it to the backend port (bypassing the Kong gateway) returns the same data, proving back ends accept bearer tokens directly. Certificate transparency and port scans expose alternative hostnames to target. Decoding the token on jwt.io shows roles that enable hidden API endpoints. Compromised CDN JS can steal keystrokes, but enforcing subresource integrity, private endpoint policies (source VPC), gateway-only token exchange, rate limits and gateway-side caching blocks these attacks.
