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.

Drupal 5.x before 5.13 and 6.x before 6.7 does not delete all related content when an input format is deleted, which prevents the content from being properly filtered and allows remote attackers to conduct cross-site scripting (XSS) attacks via unspecified vectors.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, uses an insecure hash when signing requests, which allows remote attackers to impersonate other users and gain privileges.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not sign all required data in requests, which has unspecified impact, probably related to man-in-the-middle attacks that modify critical data and allow remote attackers to impersonate other users and gain privileges.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not use timeouts for signed requests, which allows remote attackers to impersonate other users and gain privileges via a replay attack that sends the same request.

Multiple cross-site scripting (XSS) vulnerabilities in Drupal Content Construction Kit (CCK) 5.x through 5.x-1.8 allow remote authenticated users with "administer content" permissions to inject arbitrary web script or HTML via the (1) "field label," (2) "help text," or (3) "allowed values" settings.

Cross-site request forgery (CSRF) vulnerability in Live 5.x before 5.x-0.1, a module for Drupal, allows remote attackers to hijack the authentication of unspecified privileged users for requests that can be leveraged to execute arbitrary PHP code.

Cross-site scripting (XSS) vulnerability in Refine by Taxonomy 5.x before 5.x-0.1, a module for Drupal, allows remote attackers to inject arbitrary web script or HTML via a taxonomy term, which is not properly handled by refine_by_taxo when displaying tags.

Cross-site scripting (XSS) vulnerability in the eTracker module before 6.x-1.2 for Drupal allows remote attackers to inject arbitrary web script or HTML by appending a crafted string to an arbitrary URL associated with the Drupal site.

Cross-site scripting (XSS) vulnerability in the Workflow module 5.x-2.x before 5.x-2.6 and 6.x-1.x before 6.x-1.4 for Drupal, when used with the Token module, might allow remote authenticated users to inject arbitrary web script or HTML via a certain Comment field.

Cross-site scripting (XSS) vulnerability in the Context module before 6.x-2.0-rc4 for Drupal allows remote authenticated users, with Administer Blocks privileges, to inject arbitrary web script or HTML via a block description.
