Description
NornicDB through 1.4.1 contains a missing authorization vulnerability that allows authenticated users to bypass per-database read restrictions on the /nornicdb/search and /nornicdb/similar endpoints. Viewer-role users allowlisted for a database but denied read can submit search queries or node IDs to retrieve node IDs, labels and full property maps.
