What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Paytm Payment Gateway WordPress plugin before 2.8.9 does not properly escape data taken from payment callbacks before using it in a SQL statement, and the integrity check on those callbacks can be forged when the gateway is enabled without credentials, allowing unauthenticated users to perform SQL injection attacks.
