Summary
org.xwiki.platform:xwiki-platform-rendering-xwiki vulnerable to stored cross-site scripting via HTML and raw macro
Details

Impact

The HTML macro does not systematically perform a proper neutralization of script-related html tags. As a result, any user able to use the html macro in XWiki, is able to introduce an XSS attack. This can be particularly dangerous since in a standard wiki, any user is able to use the html macro directly in their own user profile page.

Patches

The problem has been patched in XWiki 14.8RC1. The patch involve that the HTML macro are systematically cleaned up whenever the user does not have script right.

Workarounds

There's no workaround for this issue.
