CVE-2026-73249 calibre Content Server `/book-update-annotations` Missing Write Authorization Check Allows Unauthorized Annotation Modification

calibre is an e-book manager. Prior to 9.12.0, the calibre Content Server endpoint POST /book-update-annotations/libraryid/bookid/fmt in src/calibre/srv/books.py omits needsdbwrite=True, causing Router.dispatch to skip ctx.checkforwriteaccess before updateannotations passes attacker-controlled JS...
