Private shelf-name disclosure via unauthorized removal errors
Published Nov 15, 2024 · Updated Nov 15, 2024
Information disclosure in Calibre-Web before 0.6.15 allows remote authenticated users to read other users' private shelf names. The cps/shelf.py remove_from_shelf route interpolates shelf.name into its 403 response after rejecting removal from a shelf the requester does not own. Any authenticated account that can submit a removal request with another user's shelf identifier can learn that shelf's name, but cannot modify the shelf through this flaw.
