Description The issue allows any user with edit rights on a page to 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.

For versions prior to 14.10.1, upgrade to version 14.10.1 or later. For versions prior to 15.0-rc-1, upgrade to version 15.0-rc-1 or later.
