Summary
Drupal is prone to multiple cross-site scripting (XSS) vulnerabilities in CKEditor.
Insight

An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more XSS vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.
