Description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.9.0, 17.4.6, and 16.10.13, it's possible using comments to inject CSS that would transform the full wiki in a link area leading to a malicious page. This vulnerability is fixed in 17.9.0, 17.4.6, and 16.10.13.
