Published 1 June 2025Updated 1 June 2026

Lab environment

Each SQLi lab spins up an isolated web app with intentional SQL concatenation bugs. Your browser connects to the sandbox — no local setup.

Exercise progression

Easy: classic ' OR 1=1 -- login bypass. Medium: UNION SELECT column enumeration and data dump. Hard: blind boolean/time-based extraction.

Tools needed

Browser and DevTools for starters. Burp Suite optional for intercepting requests. Tutorial shows raw payloads first.

After the lab

Write a 3-sentence summary: vulnerability, payload, fix (parameterized queries). Add to portfolio.
