What is CVE-2021-4450?

The Post Grid plugin for WordPress is susceptible to blind SQL injection due to inadequate escaping of user-supplied parameters and incomplete preparation of the SQL queries. Authenticated attackers with contributor-level permissions or higher can exploit this vulnerability by injecting additional SQL commands into existing queries.
