XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions it's possible to execute a content with the right of any user via a crafted URL. A user must have `programming` privileges in order to exploit this vulnerability. This issue has been patched in XWiki 14.10.7 and 15.2RC1. Users are advised to upgrade. There are no known workarounds for for this vulnerability.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
