KCFinder provides a file-management dialog for CKEditor 4. It included two vulnerabilities:
- It allowed a "reflected" cross-site scripting (XSS) attack.
- It bypassed a CiviCRM policy option which limits file-uploads. (This bypass was still subject to other restrictions. The likely impact is to allow a "stored" XSS attack. However, it is possible for there to be other impacts.)
