* Advisory ID: DRUPAL-SA-CONTRIB-2017-019 * Project: Metatag [1] (third-party module) * Version: 7.x * Date: 2017-February-15 * Security risk: 11/25 ( Moderately Critical) AC:Complex/A:None/CI:Some/II:None/E:Proof/TD:Uncommon [2] * Vulnerability: Information Disclosure

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

This module enables you to add a variety of meta tags to a site for helping with a site's search engine results and to customize how content is shared on social networks.

The module doesn't sufficiently protect against data being cached that might contain information related to a specific user.

This vulnerability is mitigated by the fact that a site must have a page with sensitive data in the page title that varies per logged in user.

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

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

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

* Metatag 7.x-1.x versions prior to 7.x-1.21.

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

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

Install the latest version:

* If you use the Metatag module for Drupal 7.x, upgrade to Metatag 7.x-1.21 [5].

Also see the Metatag [6] project page.
