XWiki Platform is a generic wiki platform. Starting in version 9.7-rc-1 and prior to versions 15.10.11, 16.4.1, and 16.5.0, any user with an account can perform arbitrary remote code execution by adding instances of "XWiki.WikiMacroClass" to any page.

It is possible to manually apply the patch to the page "XWiki.XWikiSyntaxMacrosList" as a workaround.
