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.

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.

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."

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.

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.

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."

Cross-site scripting (XSS) vulnerability in the Taxonomy Autotagger module 5.x before 5.x-1.8 for Drupal allows remote authenticated users, with create or edit post permissions, to inject arbitrary web script or HTML via unspecified vectors.

SQL injection vulnerability in the Taxonomy Autotagger module 5.x before 5.x-1.8 for Drupal allows remote authenticated users, with create or edit post permissions, to execute arbitrary SQL commands via unspecified vectors.

The Organic Groups (OG) module 5.x before 5.x-7.3 and 6.x before 6.x-1.0-RC1, a module for Drupal, allows remote attackers to obtain sensitive information (private group names) via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the Organic Groups (OG) module 5.x before 5.x-7.3 and 6.x before 6.x-1.0-RC1, a module for Drupal, allows remote authenticated users, with group owner permissions, to inject arbitrary web script or HTML via unspecified vectors.

The Outline Designer module 5.x before 5.x-1.4 for Drupal changes each content reader's authentication level to match that of the content author, which might allow remote attackers to gain privileges.

Cross-site scripting (XSS) vulnerability in the Tinytax module (aka Tinytax taxonomy block) 5.x before 5.x-1.10-1 for Drupal allows remote authenticated users to inject arbitrary web script or HTML, probably by creating a crafted taxonomy term.
