Impact

It’s possible for a user to execute anything with the right of the author of the XWiki.ClassSheet document.

Steps to Reproduce:

2. Edit your user profile with the wiki editor and add the syntax {{async}}{{groovy}}println("Hello " + “from groovy!”){{/groovy}}{{/async}}
3. Click “Save & View”

Expected result:
