CVE-2022-39322
Field-level access-control bypass for multiselect field
Description
#### Impact `@keystone-6/[email protected] || 2.3.0` users who are using the `multiselect` field, and provided field-level access control - are vulnerable to their field-level access control not being used. List-level access control is **NOT** affected. Field-level access control for fields other than `multiselect` are **NOT** affected. Example, **you are vulnerable if** you are using field-level access control on a `multiselect` like the following: ```ts const yourList = list({ access: { // this is list-level access control, this is NOT impacted }, fields: { yourFieldName: multiselect({ // this is field-level access control, for multiselect fields // this is vulnerable access: { create: ({ session }) => session?.data.isAdmin, update: ({ session }) => session?.data.isAdmin, }, options: [ { value: 'apples', label: 'Apples' }, { value: 'oranges', label: 'Oranges' }, ], // ... }), // ... }, // ... }); ``` #### Mitigation Please upgrade to `@keystone-6/core >= 2.3.1`, where this vulnerability has been closed. #### Workarounds If for some reason you cannot upgrade your dependencies, you should stop using the `multiselect` field. #### Credits Thanks to [Marek R](https://github.com/marekryb) for reporting and submitting the pull request to fix this problem.
