Summary
It's possible to execute anything with the rights of the author of a macro which uses the {{wikimacrocontent}} macro
Details

Impact

The {{wikimacrocontent}} executes the content with the rights of the wiki macro author instead of the caller of that wiki macro. This makes possible to inject scripts through it and they will be executed with the rights of the wiki macro (very often a user which has Programming rights).

Fortunately, no such macro exists by default in XWiki Standard but one could have been created or installed with an extension.

Patches

It has been patched in versions XWiki 12.6.3, 11.10.11 and 12.8-rc-1.

Workarounds

There is no easy workaround other than disabling the affected macros. Inserting content in a safe way or knowing what is the user who called the wiki macro is not easy.
