• 💡 General suggestions: The changes made in this PR seem to be well thought out and are likely to improve the security checks related to anonymous user access. However, it would be beneficial to include tests that verify the new functionality and changes.

• 🤖 Code feedback:

  • relevant file: rules/anonymous-access-enabled/raw.rego
    suggestion: Consider adding error handling for the case when the subject is not found in the rolebinding. This will prevent potential runtime errors. [important]
    relevant line: subject := rolebinding.subjects[i]

  • relevant file: rules/anonymous-access-enabled/raw.rego
    suggestion: It might be helpful to include more specific details in the alert message, such as the specific permissions that the anonymous user has been granted. This will provide more context to the user and help them understand the severity of the issue. [medium]
