The private filesystem in Drupal 5.x before 5.10 and 6.x before 6.4 trusts the MIME type sent by a web browser, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks by uploading files containing arbitrary web script or HTML.

Multiple cross-site request forgery (CSRF) vulnerabilities in Drupal 5.x before 5.10 and 6.x before 6.4 allow remote attackers to hijack the authentication of administrators for requests that (1) add or (2) delete user access rules.

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.

Interpretation conflict in Drupal 4.7.x before 4.7.11 and 5.x before 5.6, when Internet Explorer 6 is used, allows remote attackers to conduct cross-site scripting (XSS) attacks via invalid UTF-8 byte sequences, which are not processed as UTF-8 by Drupal's HTML filtering, but are processed as UTF-8 by Internet Explorer, effectively removing characters from the document and defeating the HTML protection mechanism.

Cross-site scripting (XSS) vulnerability in the Devel module before 5.x-0.1 for Drupal allows remote attackers to inject arbitrary web script or HTML via a site variable, related to lack of escaping of the variable table.
