The editor deletion form in BUEditor 4.7.x before 4.7.x-1.0 and 5.x before 5.x-1.1, a module for Drupal, does not follow Drupal's Forms API submission model, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and delete custom editor interfaces.

Cross-site scripting (XSS) vulnerability in the BUEditor module 5.x before 5.x-1.2 and 6.x before 6.x-1.4, a module for Drupal, allows remote attackers to inject arbitrary web script or HTML via input to the "plain textarea editor."
