The module doesn't sufficiently check access when responding to certain filtered collection requests, thereby causing an access bypass vulnerability. In order to fix this issue, two new hooks were added: hook_jsonapi_ENTITY_TYPE_filter_access() and hook_jsonapi_entity_field_filter_access(). Sites with custom entity types and/or with entity or field access customizations may need to implement these newly introduced hooks. Solution: Install the latest version: If you use the JSON:API module 8.x-1.x for Drupal 8.x, upgrade to JSON API 8.x-1.24 Also see the JSON:API project page.
