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


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.


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


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.
