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 request forgery (CSRF) vulnerability in Drupal 5.x before 5.8 and 6.x before 6.3 allows remote attackers to perform administrative actions via vectors involving deletion of "translated strings."

SQL injection vulnerability in the Schema API in Drupal 6.x before 6.3 allows remote attackers to execute arbitrary SQL commands via vectors related to "an inappropriate placeholder for 'numeric' fields."

Session fixation vulnerability in Drupal 5.x before 5.9 and 6.x before 6.3, when contributed modules "terminate the current request during a login event," allows remote attackers to hijack web sessions via unknown vectors.

Cross-site request forgery (CSRF) vulnerability in Drupal 6.x before 6.3 allows remote attackers to perform administrative actions via vectors involving deletion of OpenID identities.

The Drupal filter_xss_admin function in 5.x before 5.8 and 6.x before 6.3 does not "prevent use of the object HTML tag in administrator input," which has unknown impact and attack vectors, probably related to an insufficient cross-site scripting (XSS) protection mechanism.

Multiple cross-site scripting (XSS) vulnerabilities in Drupal 6.x before 6.3 allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) free tagging taxonomy terms, which are not properly handled on node preview pages, and (2) unspecified OpenID values.

Multiple SQL injection vulnerabilities in the Aggregation module 5.x before 5.x-4.4 for Drupal allow remote attackers to execute arbitrary SQL commands via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in the Aggregation module 5.x before 5.x-4.4 for Drupal allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Node Hierarchy module 5.x before 5.x-1.1 and 6.x before 6.x-1.0 for Drupal does not properly implement access checks, which allows remote attackers with "access content" permissions to bypass restrictions and modify the node hierarchy via unspecified attack vectors.

SQL injection vulnerability in the LifeType (formerly pLog) module for Drupal allows remote attackers to execute arbitrary SQL commands via the albumId parameter in a ViewAlbum action to index.php.
