Broken Access Control — IDOR, Privilege Escalation & RBAC Explained (OWASP #1)

One missing AND clause in a SQL query — and every user's data is exposed.

Broken access control is the #1 vulnerability on the OWASP Top 10. Not XSS. Not SQL injection. Access control.

In this video, we break down:
→ RBAC — how roles map to permissions to resources
→ IDOR — the most common access control bug (and the one-line fix)
→ Privilege Escalation — when users promote themselves to admin
→ Hidden UI trap — why hiding a button is not security
→ 3 defense rules that actually work in production

Every example in this video is a mistake I've seen in real codebases.
