CVE-2026-71241

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.

Summary		(es) Los puntos finales de la API de Flask del Sistema de Gestión de Libros /student, /record, /books, /find_stu_book y /find_not_return_book carecen del decorador @login_required que protege las rutas hermanas (/search_student, /storage) en el mismo archivo. Esto permite a cualquier usuario remoto no autenticado recuperar la PII del estudiante (nombre, género, validez de la tarjeta, estado de la deuda) y el historial completo de préstamos de libros al proporcionar un card_id. Debido a que los valores de card_id son enteros secuenciales, toda la base de datos de estudiantes puede ser enumerada sin autenticación.
