    "summary": "### Scope note This endpoint does not exist in v3.7.3 or on master. It was introduced on the development branch by commit `9b8e8956f` on 2026-07-27 and is present on the current development head. No released stable version is affected. ### Summary `/api/av/getAttributeViewSearchTarget` is registered with `CheckAuth` only and performs no authorization of any kind. Given a database identifier and a keyword, it searches that database's rows and returns matching content, regardless of whether the caller may see the database, the rows, or the notebook holding them. Commit `64c26e74b` on 2026-07-26 closed a reader-reachable gap on `getAttributeViewFieldViews` by adding `CheckReadonly` at router line 536. `9b8e8956f`, the following day, registered this endpoint at line 535 without it. The new route returns more than the one that was just closed: row content rather than field-visibility metadata. ### Details **Route.** `kernel/api/router.go:535` on the development branch: ```go ginServer.Handle(\"POST\", \"/api/av/getAttributeViewSearchTarget\", model.CheckAuth, getAttributeViewSearchTarget) ``` No `CheckReadonly`, no `CheckAdminRole`. **Handler.** `kernel/api/av.go` parses its arguments and calls `model.GetAttributeViewSearchTarget(id, keywords)`. `IsReadOnlyRoleContext`, `publishAccess` and any encrypted-notebook check are all absent. The sink is `kernel/model/attribute_view_render.go:69`. **The adjacent routes make the omission stark.** Lines 533 to 541 all handle the same data class:",
