XWiki Commons are technical libraries common to several other top level XWiki projects. Starting in version 3.1-milestone-1, any user can edit their own profile and inject code, which is going to be executed with programming right. The same vulnerability can also be exploited in all other places where short text properties are displayed, e.g., in apps created using Apps Within Minutes that use a short text field. The problem has been patched on versions 13.10.9, 14.4.4, 14.7RC1.

org.xwiki.commons:xwiki-commons-xml is a common module used by other XWiki top level projects. Starting in version 2.7 and prior to versions 12.10.10, 13.4.4, and 13.8-rc-1, it is possible for a script to access any file accessing to the user running XWiki application server with XML External Entity Injection through the XML script service. The problem has been patched in versions 12.10.10, 13.4.4, and 13.8-rc-1. There is no easy workaround for fixing this vulnerability other than upgrading and being careful when giving Script rights.
