# CVE-2026-90941

> 5.3 MEDIUM · 🧪 PoC

## Beschreibung

novel-plus through 5.3.3 contains an authorization bypass vulnerability in the BookController download endpoint that allows authenticated backend accounts to export complete book text including paid chapters. Attackers can supply a bookId and bookName to retrieve all chapter content without VIP or purchase verification, bypassing the permission checks and data-scope limits enforced elsewhere in the admin interface.
