Description
The Calendar plugin for WordPress is vulnerable to SQL Injection via the plugin's shortcodes in all versions up to, and including, 1.3.14 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor access or higher, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
