Any user with edit rights on a page (e.g., it's own user page), can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the information loaded from attachments in imported.vm, importinline.vm, and packagelist.vm. This page is installed by default.
Reproduction steps are described in https://jira.xwiki.org/browse/XWIKI-20267
The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.1, 14.4.8, and 13.10.11.
The issue can be fixed by applying this patch on imported.vm, importinline.vm, and packagelist.vm.
