## Lab 1: [SQL injection vulnerability in WHERE clause allowing retrieval of hidden data](https://portswigger.net/web-security/sql-injection/lab-retrieve-hidden-data)

{% hint style="info" %}
Mô tả:\
This lab contains a SQL injection vulnerability in the product category filter. When the user selects a category, the application carries out a SQL query like the following:

`SELECT * FROM products WHERE category = 'Gifts' AND released = 1`

To solve the lab, perform a SQL injection attack that causes the application to display one or more unreleased products.
