Understand common web application attacks with real examples, how they work, and how to defend against them. Educational use only — be a better developer.
A malicious user inserts SQL code into an input field to manipulate the database.
Attacker injects malicious scripts into pages viewed by other users, stealing sessions or redirecting victims.
Tricks authenticated users into submitting unintended requests — such as changing passwords or transferring funds — from another site.
Automated tools attempt thousands of password combinations per minute to compromise user accounts or abuse API endpoints.

Attacker steals or predicts a valid session token to impersonate an authenticated user without knowing their password.
Attacker manipulates file path inputs using ../ sequences to access files outside the intended directory, including system files.
