CVE-2025-12126Network attack vector

Authenticated book manipulation via unchecked object keys

Published Nov 11, 2025 · Updated Nov 11, 2025

Authorization bypass in The Total Book Project 1.0 and earlier allows remote authenticated users to alter other users' books. Several AJAX chapter-management handlers trust a client-supplied book key without verifying that the requester owns the referenced book. Contributor-level access is sufficient to create, move, or delete chapters in books outside the requester's control, affecting stored content integrity.
