A vulnerability, which was classified as critical, was found in XWiki xwiki-platform-oldcore 13.10.11/14.4.8/14.10.2/15.0RC1 (Content Management System). Affected is an unknown function of the component User Profile Handler. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94.

This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can edit their own user profile can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The same vulnerability can also be exploited in other contexts where the `display` method on a document is used to display a field with wiki syntax, for example in applications created using `App Within Minutes`. This has been patched in XWiki 13.10.11, 14.4.8, 14.10.2 and 15.0RC1. There is no workaround apart from upgrading.
