AI risk analysis

Summary: The flaw allows unauthorized access to sensitive API endpoints by enumerating card_id values, compromising user data security.
Exploitability: Exploitation is relatively easy due to sequential card_id values and missing authentication checks.
Blast radius: If exploited, it could lead to full enumeration of the student database, posing a significant risk to user privacy.
Prioritized remediation: Apply the @login_required decorator to all relevant API endpoints to enforce proper authentication.

NVD description

Book-Management-System's Flask API endpoints /student, /record, /books, /find_stu_book, and /find_not_return_book are missing the @login_required decorator that protects sibling routes (/search_student, /storage) in the same file. Because card_id values are sequential integers, the entire student database can be enumerated without authentication.
