Drupal — система управления контентом с открытым исходным кодом. На Drupal работает более миллиона сайтов — от личных блогов до сайтов компаний, политических партий и государственных организаций.

The OpenID module in Drupal 6.x before 6.18, and the OpenID module 5.x before 5.x-1.4 for Drupal, violates the OpenID 2.0 protocol by not checking for reuse of openid.response_nonce values, which allows remote attackers to bypass authentication by leveraging an assertion from an OpenID provider.

Multiple cross-site scripting (XSS) vulnerabilities in the Views module 6.x before 6.x-2.11 for Drupal allow remote attackers to inject arbitrary web script or HTML via (1) a URL or (2) an aggregator feed title.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Views UI implementation in the Views module 5.x before 5.x-1.8 and 6.x before 6.x-2.11 for Drupal allow remote attackers to hijack the authentication of administrators for requests that (1) enable all Views or (2) disable all Views.

Cross-site scripting (XSS) vulnerability in the Views module 6.x before 6.x-2.12 for Drupal allows remote attackers to inject arbitrary web script or HTML via a page path.

Multiple cross-site scripting (XSS) vulnerabilities in revisioning_theme.inc in the Taxonomy module in the Revisioning module 6.x-3.13 and other versions before 6.x-3.14 for Drupal allow remote authenticated users with certain privileges to inject arbitrary web script or HTML via the (1) tags or (2) term parameters.

Drupal 7.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by modules/simpletest/tests/upgrade/drupal-6.upload.database.php and certain other files.

The Contact Forms module 7.x-1.x before 7.x-1.2 for Drupal does not specify sufficiently restrictive permissions, which allows remote authenticated users with the "access the site-wide contact form" permission to modify the module settings via unspecified vectors.

The filedepot module 6.x-1.x before 6.x-1.3 for Drupal, when accessed using multiple different browsers from the same IP address, causes Internet Explorer sessions to "switch users" when uploading a file, which has unspecified impact possibly involving file uploads to the wrong user directory, aka "Session Management Vulnerability."

The Janrain Capture module 6.x-1.0 and 7.x-1.0 for Drupal, when creating a local user account, allows attackers to obtain part of the initial input used to generate passwords, which makes it easier to conduct brute force password guessing attacks.

Cross-site request forgery (CSRF) vulnerability in the Addressbook module for Drupal 6.x-4.2 and earlier allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.
