The Registration Forms – User profile, Content Restriction, Spam Protection, Payment Gateways, Invitation Codes WordPress plugin before 3.7.1.6 does not properly escape user data before using it in a SQL statement in the wp-json/pie/v1/login REST API endpoint, leading to an SQL injection.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
