The Thumbnail carousel slider plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 1.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Thumbnail carousel slider WordPress plugin before 1.1.10 does not sanitise and escape some parameters before outputting them back in pages, leading to Reflected Cross-Site Scripting vulnerability which could be used against high privilege users such as admin.
The Thumbnail carousel slider plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the search_term parameter in versions up to, and including, 1.1.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
