Any user with edit right can execute arbitrary database select and access data stored in the database.
To reproduce: * In admin, rights, remove scripting rights for {{XWikiAllGroup}}. * Create a new user without any special privileges. * Create a page "Private.WebHome" with {{TOKEN_42}} as content. Go to "page administration" and explicitly set all rights for "Admin" to remove them for all other users. * Logout and login as the unprivileged user. Ensure that the previously created page cannot be viewed. * Create a new page "ExploitClass.WebHome" and then open it in the class editor (first, make the user an advanced user). * Add a field named {{ContentList}} of type {{Database List}} * Enter in field "Hibernate Query" the following content: {noformat}select doc.content, doc.fullName from XWikiDocument as doc where doc.fullName = 'Private.WebHome'{noformat} * Save the class. * Open [http://localhost:8080/xwiki/bin/view/ExploitClass/?xpage=suggest&classname=ExploitClass.WebHome&fieldname=ContentList&firCol=doc.fullName&secCol=-]
