Multiple cross-site scripting (XSS) vulnerabilities in Drupal 5.x before 5.2, and 4.7.x before 4.7.7, (1) allow remote attackers to inject arbitrary web script or HTML via "some server variables," including PHP_SELF; and (2) allow remote authenticated administrators to inject arbitrary web script or HTML via custom content type names.

The comment_form_add_preview function in comment.module in Drupal before 4.7.6, and 5.x before 5.1, and vbDrupal, allows remote attackers with "post comments" privileges and access to multiple input filters to execute arbitrary code by previewing comments, which are not processed by "normal form validation routines."

Unspecified vulnerability in Drupal before 4.6.11, and 4.7 before 4.7.5, when MySQL is used, allows remote authenticated users to cause a denial of service by poisoning the page cache via unspecified vectors, which triggers erroneous 404 HTTP errors for pages that exist.
