Protect Your WooCommerce Store: SQL Injection Vulnerability Found in PDF Invoices & Packing Slips Plugin

CVSScvssV3_1: 7.6

A SQL injection vulnerability has been discovered in the popular WooCommerce plugin “WP Overnight PDF Invoices & Packing Slips”. SQL injection attacks work by inserting malicious SQL statements into an entry field for execution by the backend database. This allows attackers to view data they shouldn’t have access to or even take control of the database and website.

In this case, the plugin was found to not properly sanitize user input on certain fields. A malicious actor could craft a specially formatted input containing SQL code to view or modify data in the database like customer details or orders. This puts sensitive customer information at risk.

SQL injection vulnerabilities are common and occur when user input is not filtered or escaped before being placed into an SQL query. Attackers manually test for locations where raw input is placed into queries and then try various SQL code to determine if it executes.

If you use this plugin, you should update to the latest version immediately to patch this vulnerability. Also ensure your WooCommerce and WordPress installations are up to date. Use a strong and unique password. Consider enabling additional security measures like two-factor authentication if available. Staying on top of updates is one of the best ways to protect your store from these types of attacks.
