GHSA-588f-fvcv-xhvf: Note Mark: Unauthenticated disclosure of soft-deleted note metadata via deleted=true on public booksCVE-2026-50554
0

An unauthenticated API endpoint in the Note Mark backend allows disclosure of metadata for soft-deleted (trashed) notes belonging to public books. The endpoint GET /api/books/{bookID}/notes accepts a 'deleted=true' query parameter that bypasses the soft-delete filter but still permits access if the book is public. This results in exposure of note metadata such as id, title, slug, and timestamps to unauthenticated users, even though the note owner intended these notes to be hidden. The note content itself is not exposed. The vulnerability arises from improper authorization logic that does not restrict soft-deleted notes to their owners only. A code fix involves restricting soft-deleted note listings exclusively to the book owner, preventing public access to trashed notes.
