Draft List is a WordPress plugin to manage and promote unpublished content. Versions 2.6.3 and below are vulnerable to stored Cross-Site Scripting (XSS) in the [drafts] shortcode and Draft List widget when the documented custom template option places the {{draft}} placeholder inside an HTML attribute. The vulnerable code inserts the raw draft post_title into {{draft}} when the current viewer cannot edit posts. Because the template is sanitized before {{draft}} replacement, a Contributor can store a quote-only title payload that breaks out of an attribute in a site-configured Draft List template and executes JavaScript for visitors who load the public page. Version 2.6.4 fixes the issue.
