Services for Drupal 7- Moderately critical - Access bypass - SA-CONTRIB-2020-022

Project: Services
Version: 7.x-3.x-dev
Date: 2020-June-03
Security risk: Moderately critical 11∕25
Vulnerability: Access bypass

Description

This module provides a standardized solution for building API's so that external clients can communicate with Drupal.

The module's taxonomy term index resource doesn't take into consideration certain access control tags provided (but unused) by core, that certain contributed modules depend on.

This vulnerability is mitigated by the fact your site must have the taxonomy term index resource enabled, your site must have a contributed module enabled which utilizes taxonomy term access control, and an attacker must know your api endpoint's path.

Solution

Install the latest version:

If you use the Services module for Drupal 7.x, upgrade to Services 7.x-3.26
