What the vulnerability does
01Description
The Welcart e-Commerce plugin for WordPress is vulnerable to SQL Injection via the cookie in all versions up to, and including, 2.11.21 due to insufficient escaping on the user supplied value and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
