XWiki Commons are technical libraries common to several other top level XWiki projects. Rights added to a document are not taken into account for viewing it once its deleted. Note that this vulnerability only impact deleted documents that where containing view rights: the view rights provided on a space of a deleted document are properly checked. The problem has been patched in XWiki 14.10 by checking the rights of current user: only admin and deleter of the document are allowed to view it.
The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

Resources such as files and directories may be inadvertently exposed through mechanisms such as insecure permissions, or when a program accidentally operates on the wrong object. For example, a program may intend that private files can only be provided to a specific user. This effectively defines a control sphere that is intended to prevent attackers from accessing these private files. If the file permissions are insecure, then parties other than the user will be able to access those files. A separate control sphere might effectively require that the user can only access the private files, but not any other files on the system. If the program does not ensure that the user is only requesting private files, then the user might be able to access other files on the system. In either case, the end result is that a resource has been exposed to the wrong party.
