Access control is crucial for modern web development as it enables the management of how subjects (users, processes, and devices) should be granted permissions to application functions and resources. Access control mechanisms also determine the level of access permitted and manifest activities carried out by specific entities. Broken access control vulnerabilities arise when a malicious user abuses the constraints on the actions they are allowed to perform or the objects they can access. Attackers typically leverage access control failures to gain unauthorized access to resources within the application, run malicious commands, or gain a privileged user‘s permission.

This guide discusses broken access control vulnerabilities, the severity of associated attacks, and common prevention techniques.
