Don't Get Burned! Secure Coding Essentials in Java to protect your application.

Live demos show SQL injection via string concatenation (copilot-generated search code lets an attacker run "update product set price=0"), file upload path traversal by uploading ../ in filename (burp suite proxy writes a file into project root), and XML XXE reading /etc/passwd. Replacements: use prepared/parameterized queries, validate or normalize file paths, disable DTD/external entities in XML parsers. Recommendations include Argon2id for password hashing with migration strategy, AES-GCM for encryption modes, update frameworks, scan dependencies, and return DTOs instead of raw entities.
