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 Organic Groups (OG) module 7.x-1.x before 7.x-1.5 for Drupal does not properly maintain pending group memberships, which allows remote authenticated users to post to arbitrary groups by modifying their own account while a pending membership is waiting to be approved.

Cross-site request forgery (CSRF) vulnerability in the BrowserID (Mozilla Persona) module 7.x-1.x before 7.x-1.3 for Drupal allows remote attackers to hijack the authentication of arbitrary users for requests that login a user to another web site.

Multiple cross-site request forgery (CSRF) vulnerabilities in the RESTful Web Services (RESTWS) module 7.x-1.x before 7.x-1.1 and 7.x-2.x before 7.x-2.0-alpha3 for Drupal allow remote attackers to hijack the authentication of arbitrary users via unknown vectors.

Drupal 6.x before 6.31 and 7.x before 7.27 does not properly isolate the cached data of different anonymous users, which allows remote anonymous users to obtain sensitive interim form input information in opportunistic situations via unspecified vectors.

The RESTful Web Services (RESTWS) module 7.x-1.x before 7.x-1.3 and 7.x-2.x before 7.x-2.0-alpha5 for Drupal, when page caching is enabled and anonymous users are assigned RESTWS permissions, allows remote attackers to cause a denial of service via a GET request with an HTTP Accept header set to a non-HTML type, which can "interfere with Drupal's page cache."

Cross-site scripting (XSS) vulnerability in the Search API Sorts module 7.x-1.x before 7.x-1.4 for Drupal allows remote authenticated users with certain roles to inject arbitrary web script or HTML via unspecified field labels.

The admin page in the Banckle Chat module for Drupal does not properly restrict access, which allows remote attackers to bypass intended restrictions via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in the Varnish module 6.x-1.x before 6.x-1.2 and 7.x-1.x before 7.x-1.0-beta2 for Drupal allow remote attackers to inject arbitrary web script or HTML via crafted a (1) Watchdog message or (2) admin setting.

Cross-site scripting (XSS) vulnerability in Views in the Search API (search_api) module 7.x-1.x before 7.x-1.4 for Drupal, when using certain backends and facets, allows remote attackers to inject arbitrary web script or HTML via unspecified input, which is returned in an error message.

The printer friendly version functionality in the Book module in Drupal 6.x before 6.28 and 7.x before 7.19 does not properly restrict access to node that are part of a book outline, which allows remote authenticated users with the "access printer-friendly version" permission to read node titles and possibly node content via unspecified vectors.
