email verification. Before versions 14.2 and 13.10.4, this can also be exploited on a private wiki, thus potentially giving the attacker access to the wiki. Depending on the configured default rights of users, this could also give attackers write access to an otherwise read-only public wiki. Users can also be created when an external authentication system like LDAP is configured, but authentication fails unless the authentication system supports a bypass/local accounts are enabled in addition to the external authentication system. This issue has been patched in XWiki 13.10.5 and 14.3RC1. As a workaround, one may replace `xpart.vm`, the entry point for this attack, by a patched version from the patch without updating XWiki.
