* Advisory ID: DRUPAL-SA-CONTRIB-2016-021 * Project: Boost [1] (third-party module) * Version: 7.x * Date: 2016-April-13 * Security risk: 11/25 ( Moderately Critical) AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2] * Vulnerability: Information Disclosure

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

This module provides static page caching for Drupal enabling a very significant performance and scalability boost for sites that receive mostly anonymous traffic.

The module doesn't prevent form cache from leaking between anonymous users which could result in information disclosure, where one user sees form data generated for another.

This vulnerability is mitigated by the fact that it only affects AJAX forms which expose sensitive data to anonymous users.

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

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

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

* Boost 7.x-1.x versions prior to 7.x-1.1.

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

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

Install the latest version:

* If you use the Boost module for Drupal 7.x, upgrade to Boost 7.x-1.1 [5]

Also see the Boost [6] project page.
