Vulnerabilities

The SupportCandy WordPress plugin before 3.1.7 does not properly sanitise and escape the `id` parameter for an Agent in the REST API before using it in an SQL statement, leading to an SQL Injection exploitable by users with a role as low as Subscriber.

The SupportCandy WordPress plugin before 3.1.5 does not validate and escape user input before using it in an SQL statement, which could allow unauthenticated attackers to perform SQL injection attacks

The SupportCandy WordPress plugin before 2.2.7 does not have CSRF check in the wpsc_tickets AJAX action, nor has any sanitisation or escaping in some of the filter fields which could allow attackers to make a logged in user having access to the ticket lists dashboard set an arbitrary filter (stored in their cookies) with an XSS payload in it.

An Unrestricted File Upload Vulnerability in the SupportCandy plugin through 2.0.0 for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension.
