Technical Analysis

Despite the CVE being registered for Wordpress, fckeditor is embedded in many CMS or custom applications and as such can impact more applications. However, fckeditor provides connectors for ASP, PHP, etc. but not JSP for example. So a Java app using fckeditor may be not vulnerable even with a vulnerable fckeditor.
