Earlier I wrote about two other vulnerabilities.

These are Abuse of Functionality, Denial of Service, Cross-Site Scripting
and Full path disclosure vulnerabilities in Js-Multi-Hotel plugin for
WordPress. There are much more vulnerabilities in this plugin (including
dangerous holes), so after two advisories I'll write new advisories.

Besides conducting DoS attack manually, it's also possible to conduct
automated DoS and DDoS attacks with using of DAVOSET
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2013-June/008850.html).

DDoS attacks via other sites execution tool:
