XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions its possible to display or interact with any page a user cannot access through the combination of the async and display macros. A comment with either macro will be executed when viewed providing a code injection vector in the context of the running server. This vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11. Users are advised to upgrade. There are no known workarounds for this issue.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
