CVE-2026-71241: LYRIC777 Book-Management-System

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
