Description

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.
