Vulnerability Overview

The Paid Memberships Pro WordPress plugin before 2.6.7 does not escape the discount_code in one of its REST route (available to unauthenticated users) before using it in a SQL statement, leading to a SQL injection

Technical Analysis

REMEDIATION: Update to version 2.6.7, or a newer patched version --- IDENTIFIER: CWE-89 (Improper 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.
