Project: JSON API [1]
Version: 8.x-1.15
Date: 2018-April-25
Security risk: *Moderately critical* 11∕25
AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Cross Site Request Forgery

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

The module doesn't provide CSRF protection when processing authenticated
traffic using cookie-based authentication.

This vulnerability is mitigated by the fact that an attacker must be allowed
to create or modify entities of a certain type, and a very specific and
uncommon CORS configuration that allows all other pre-checks to be skipped.

Solution: 
Install the latest version:

  * If you use the JSON API module for Drupal 8.x, upgrade to 8.x-1.16 [3]
