Field-level access-control bypass for multiselect field
#### Impact
`@keystone-6/core@2.2.0 || 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.
