CVE-2026-71241 lyric777 CVE debrief

AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-05T11:16:26.997Z and has not been modified since then. CVE-2026-71241 is a high-severity vulnerability in Book-Management-System's Flask API. The /student, /record, /books, /find_stu_book, and /find_not_return_book endpoints are missing the @login_required decorator, allowing unauthenticated remote users to retrieve sensitive student information, including PII and full book-borrowing history. The sequential integer nature of card_id values enables enumeration of the entire student database without authentication. Administrators and users of the Book-Management-System, particularly those with access to sensitive student information, should be aware of this vulnerability and take immediate action to review and remediate the affected endpoints. Review and apply the @login_required decorator to the affected Flask API endpoints, verify and remediate the /student, /record, /books, /find_stu_book, and /find_not_return_book endpoints, implement compensating controls, such as IP restrictions or rate limiting, until remediation is complete, monitor for suspicious activity and potential enumeration attempts, and update inventory records to reflect the vulnerability and remediation status.

Recommended defensive actions

  • Review and apply the @login_required decorator to the affected Flask API endpoints
  • Verify and remediate the /student, /record, /books, /find_stu_book, and /find_not_return_book endpoints
  • Implement compensating controls, such as IP restrictions or rate limiting, until remediation is complete
  • Monitor for suspicious activity and potential enumeration attempts
  • Update inventory records to reflect the vulnerability and remediation status

Evidence notes

The CVE description indicates that several Flask API endpoints in Book-Management-System are missing the @login_required decorator, allowing unauthenticated access to student PII and book-borrowing history. The card_id values are sequential integers, enabling enumeration of the entire student database without authentication.
