What the vulnerability does

01Description

The Modern Events Calendar Lite plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 7.21.9. This is due improper or insufficient validation of the id property when exporting calendars. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.
