JSON:API - Moderately critical - Access bypass - SA-CONTRIB-2018-081

Project: JSON:API
Date: 2018-December-19
Security risk: Moderately critical 13/25
AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:All
Vulnerability: Access bypass

Description:

This module provides a JSON:API specification-compliant HTTP API for accessing
and manipulating Drupal content and configuration entities.

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.
