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 in software that interfaces with databases. Programmers need to ensure any user input is cleaned before running database queries. Input should be treated as untrusted by default.

If you use this plugin, you should update to the latest version immediately as it fixes this security issue. Also ensure your WooCommerce and WordPress installations are up to date. Maintaining updated software is one of the best ways to protect against known vulnerabilities.

Be vigilant of any unusual activity on your site and customer reports of issues. Consider changing passwords as a precaution. With SQL injection, attackers can potentially gain administrative access putting your whole site at risk. Staying on top of updates helps avoid such risks in the future.
