Original Bulletin: 

- --------------------------BEGIN INCLUDED TEXT--------------------

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-112
  * Project: oEmbed (third-party module)
  * Version: 6.x
  * Date: 2010-December-22
  * Security risk: Moderately Critical
  * Exploitable from: Remote
  * Vulnerability: Access Bypass

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

The oEmbed module allows a Drupal site to embed content from oEmbed-providers
as well as for a site to become an oEmbed-provider itself so that other
oEmbed-enabled websites can embed its content.

If an external site requested to embed a node, the oEmbed provider did not
check node access, resulting in content not otherwise accessable by a user to
be embeddable.

This only affects sites that are using the oEmbed Provider sub-module.

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

  * oEmbed module for Drupal 6.x versions prior to 6.x-0.8

Drupal core is not affected. If you do not use the contributed oEmbed [1]
module, together with its oEmbed provider module, there is nothing you need
to do.

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

Install the latest version:

  * If you use the oEmbed module for Drupal 6.x upgrade to oEmbed 6.x-0.8 [2].

See also the oEmbed project page [3].

- -------- REPORTED BY ---------------------------------------------------------

  * Benjamin Doherty [4]

- -------- FIXED BY ------------------------------------------------------------

  * Pelle Wessman [5], module co-maintainer
