XWiki Blog Application: Privilege Escalation (PR) from account through blog content
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The blog application in XWiki allowed remote code execution for any user who has edit right on any page. Normally, these are all logged-in users as they can edit their own user profile. To exploit, it is sufficient to add an object of type `Blog.BlogPostClass` to any page and to add some script macro with the exploit code to the "Content" field of that object.
