XWiki Platform licensing issue vulnerability

XWiki Platform is a set of wiki platforms for creating web collaboration applications from the French company XWiki. XWiki Platform versions prior to 13.10.8, 14.0 and later, and prior to 14.4.3 are vulnerable to authorization issues, which stem from incorrect privilege management and can be exploited by attackers to modify the wiki by importing a crafted XAR package to Any page.
