CVE-2026-41572: Note Mark: Unauthenticated read of notes and assets in soft-deleted public books

After a note-mark owner soft-deletes a public book, its notes and uploaded assets stay readable at /api/notes/{id}, /api/notes/{id}/content, the slug URL, and the asset endpoints. Unauthenticated callers who hold the note ID or the slug path retain access. GORM’s soft-delete scope does not reach the raw JOIN books ... clauses used by the note and asset queries.
