Broken Access Control

Writeups for PortSwigger's Broken Access Control labs — covering unprotected admin functionality, parameter-based access control methods, horizontal and vertical privilege escalation, insecure direct object references (IDOR), URL-based access control bypass, referer-based vulnerabilities, and multi-step process flaws. Each lab demonstrates step-by-step exploitation with practical insights into detection, prevention, and real-world attack scenarios.
