   * Advisory ID: DRUPAL-SA-CONTRIB-2017-056
   * Project: OAuth [1]     (third-party module)
   * Version: 8.x
   * Date: 2017-July-05
   * Security risk: 15/25 ( Critical)
     AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2]
   * Vulnerability: Access bypass

-------- DESCRIPTION
---------------------------------------------------------

This module enables you to protect requests via the OAuth authentication
protocol.

The module doesn't sufficiently notify the Cache API to avoid caching
responses under the scenario in which an authenticated user requests a
resource such as unpublished node.

This vulnerability is mitigated by the fact that an attacker must know the
available resources in a Drupal site.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED
---------------------------------------------------

   * OAuth 8.x-2.x versions prior to 8.x-2.1.

Drupal core is not affected. If you do not use the contributed OAuth [4]
module, there is nothing you need to do.

-------- SOLUTION
------------------------------------------------------------

In addition to updating the code, you must Clear all caches.

   * If you use the OAuth module for Drupal 8.x, upgrade to OAuth 8.x-2.1

Also see the OAuth [5] project page.
