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.

Cross-site scripting (XSS) vulnerability in the Wordfilter module 5.x before 5.x-1.1 and 6.x before 6.x-1.1 for Drupal allows remote authenticated users, with "administer words filtered" privileges, to inject arbitrary web script or HTML via the word list.

Cross-site scripting (XSS) vulnerability in the CiviRegister module before 6.x-1.1 for Drupal allows remote attackers to inject arbitrary web script or HTML via the URI.

Drupal cross-site scripting vulnerability via actions feature and trigger module

The comment module in Drupal 5.x before 5.23 and 6.x before 6.18 allows remote authenticated users with certain privileges to bypass intended access restrictions and reinstate removed comments via a crafted URL, related to an "unpublishing bypass" issue.

The upload module in Drupal 5.x before 5.23 and 6.x before 6.18 does not properly support case-insensitive filename handling in a database configuration, which allows remote authenticated users to bypass the intended restrictions on downloading a file by uploading a different file with a similar name.

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 ensuring that fields are signed, which allows remote attackers to bypass authentication by leveraging an assertion from an OpenID provider.

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.

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 verifying the openid.return_to value, which allows remote attackers to bypass authentication by leveraging an assertion from an OpenID provider.

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.
