CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Points Management System For Gamification, Ranks, Badges, and Loyalty Rewards Program <= 2.2 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Points Management System For Gamification, Ranks, Badges, and Loyalty Rewards Program the fix is 2.3: builds <= 2.2 are affected, anything from 2.3 onward is not.

Update to version 2.3, or a newer patched version
