Episode 80: Broken Access Control Flaws

Access control determines who can do what—and when it breaks, attackers often find a clear path in. In this episode, we take a deep dive into broken access control vulnerabilities, one of the most serious and widespread categories in application security. You’ll learn how horizontal and vertical privilege escalation works, what insecure direct object references (IDORs) are, and how misconfigured roles, permissions, or logic create dangerous exposures.

We also cover how to detect these flaws during assessments, how to write about them in reports, and how to guide remediation through principles like least privilege and role-based access control (RBAC). Whether you’re analyzing a web application or interpreting scanner results, this episode arms you with the knowledge to identify and explain a class of vulnerabilities that attackers love—and organizations often overlook.
