📋 Description

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.
