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.

 https://db.gcve.eu/vuln/ghsa-cqmq-8755-7xvh GHSA-cqmq-8755-7xvh — Keystone vulnerable to `graphql.maxTake` bypass with negative `take` 2026-10-01T10:22:22.688195+00:00

Affected: npm: @keystone-6/core

# Summary The value of `graphql.maxTake` can be bypassed by providing a negative input. This can be used to exceed the developer's intended `graphql.maxTake` value, allowing queries to return results in excess of the `graphql.maxTake` value set.

# Impact This affects any project relying on `graphql.maxTake` to bound the number of items returned per query.

# Patches This issue has been patched in `@keystone-6/core` version `6.5.3`.

If you cannot patch, you can workaround this by restricting `take` input values in your GraphQL queries to the bounded value, or by blocking negative values.
