The product does not perform an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality. The summary by CVE is:

Keystone is an open source headless CMS for Node.js — built with GraphQL and React. When `ui.isAccessAllowed` is set as `undefined`, the `adminMeta` GraphQL query is publicly accessible (no session required). This is different to the behaviour of the default AdminUI middleware, which by default will only be publicly accessible (no session required) if a `session` strategy is not defined. This vulnerability does not affect developers using the `@keystone-6/auth` package, or any users that have written their own `ui.isAccessAllowed` (that is to say, `isAccessAllowed` is not `undefined`). This vulnerability does affect users who believed that their `session` strategy will, by default, enforce that `adminMeta` is inaccessible by the public in accordance with that strategy; akin to the behaviour of the AdminUI middleware. This vulnerability has been patched in `@keystone-6/core` version `5.5.1`. Users are advised to upgrade. Users unable to upgrade may opt to write their own `isAccessAllowed` functionality to work-around this vulnerability.

The weakness was released 08/15/2023 as GHSA-9cvc-v7wm-992c. The advisory is shared at github.com. This vulnerability is known as CVE-2023-40027 since 08/08/2023. Neither technical details nor an exploit are publicly available.
