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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
