SCA: security update for @keystone-6/core (GHSA-cqmq-8755-7xvh)

high Tenable Self-Hosted Container Security Plugin ID 446236

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Keystone is a content management system for Node.js. Prior to 6.5.3, the findMany resolver in
 packages/core/src/lib/core/queries/resolvers.ts compares the signed take argument directly with
 graphql.maxTake, allowing a remote unauthenticated GraphQL client to provide a negative take value whose
 magnitude exceeds the configured bound. The bypass also applies to relationship queries and can return
 more records than the developer intended, potentially exhausting service resources. This issue is fixed in
 version 6.5.3. (CVE-2026-63421)

Solution

Update the @keystone-6/core library and its related packages to version 6.5.3 or later.
