* 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
