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. -------- REPORTED BY --------------------------------------------------------- * Matthias Hutterer [7] * torokrita [8] -------- FIXED BY ------------------------------------------------------------ * Damien McKenna [9] the module maintainer. * Klaus Purer [10] of the Drupal Security Team. -------- COORDINATED BY ------------------------------------------------------ * Damien McKenna [11] the module maintainer. * Klaus Purer [12] of the Drupal Security Team. -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at https://www.drupal.org/contact [13].
