Overview

Affected versions of this package are vulnerable to Privilege Escalation due to improper escaping in the document SkinsCode.XWikiSkinsSheet, allowing the attacker to escalate privileges from view rights on that document to programming rights. This vulnerability allows the execution of arbitrary script macros, including Groovy and Python macros that allow remote code execution, including unrestricted read and write access to all wiki contents.

Exploiting this vulnerability is possible by opening a non-existing page with a name crafted to contain a dangerous payload.
