Linkit – Moderately Critical – Access Bypass – DRUPAL-SA-CONTRIB-2017-033

Advisory ID: DRUPAL-SA-CONTRIB-2017-033
Project: Linkit- Enriched linking experience (third-party module)
Version: 8.x
Date: 2017-March-22
Security risk: 10/25 ( Moderately Critical) AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Default
Vulnerability: Access bypass

Description

Linkit provides an easy interface for internal and external linking with WYSIWYG editors by using an autocomplete field.

When searching for entities, this module doesn’t always enforce the access restrictions and users may see information about entities they should not be able to access.

This is mitigated by the fact that a user must have access to a text format that uses Linkit.

CVE identifier(s) issued

A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.

Versions affected

Linkit 8.x-4.x versions prior to 8.x-4.3.
