What is Broken access vulnerability ? OWASP Top 10

Broken access vulnerabilities refer to security flaws that allow unauthorized access to sensitive resources or actions. These vulnerabilities occur when access controls, such as user authentication or authorization, are not implemented or are implemented incorrectly.

For example, a broken access vulnerability could occur if a user is granted access to a resource or action that they should not have access to, such as viewing or editing someone else's personal information. This vulnerability could also occur if a user is able to bypass authentication measures, such as weak passwords or password reuse.

It's important to identify and address broken access vulnerabilities to prevent unauthorized access to sensitive data and resources. This can be done through implementing proper access controls, conducting regular security audits, and keeping software up-to-date with the latest security patches.
