Upstream source description

Group-Office is an enterprise customer relationship management and groupware tool. Prior to version 26.0.37, go/modules/community/bookmarks/controller/Bookmark.php's description() action takes a fully attacker-controlled url parameter and passes it, unvalidated, to \GO\Base\Util\HttpClient::request(). HttpClient::_initRequest() sets CURLOPT_URL directly from this value with no host/IP validation at all. This can result in SSRF via Bookmark/description JMAP action. This issue has been patched in version 26.0.37.
