Summary
XWiki vulnerable to click-jacking through CSS injection in comments
Details

Impact

It's possible using comments to inject CSS that would transform the full wiki in a link area leading to a malicious page. All versions of XWiki are impacted by this kind of attack.

Patches

The problem has been patched not by preventing injecting CSS in comments, which is currently a feature of XWiki, but by requiring confirmation from users when driving them to untrusted domains after clicking on a link, thus preventing any click-jacking attack. This security measure has been put in place in XWiki 17.9.0, 17.4.6, 16.10.13.

Workarounds

There's no out-of-the-box workaround, but it should be possible to partly reuse the javascript code provided for the security measure in a JSX object inside the wiki, to request the same kind of confirmation.
