Hardening RBAC and Data Boundaries in Production
Practical defenses against authorization bypass, parameter tampering, and token leaks.
Security vulnerabilities in web applications rarely stem from zero-day cryptographic exploits; they overwhelmingly stem from broken object-level authorization (BOLA) and missing authorization checks on API endpoints.
UI Visibility is Not Security
Never assume that because a button is hidden for a non-admin role, the underlying endpoint is secure. Every API handler must validate the requester's authenticated session, resolve their specific role tenant, and check resource ownership before executing queries.
