To review code for security vulnerabilities, you must validate user input, apply least-privilege controls, and secure storage. This process prevents hardcoded secrets, API authorization flaws, and unsafe file uploads before reaching production.

The best way to prevent hardcoded secrets is moving keys, tokens, and passwords into secure environment variables and managed secret stores. This prevents accidental data leaks and protects sensitive authentication credentials.

Input validation protects API endpoints by verifying user data before processing. This prevents injection, cross-site scripting (XSS), and cross-site request forgery (CSRF) vulnerabilities from exploiting unsafe data handling.

Yes, you can apply a consistent security checklist to authentication, payment flows, file uploads, and third-party API integrations. This catches missing validation, insecure storage, and unsafe error handling before launch.

Your application needs least-privilege authorization controls to limit access strictly to necessary resources. This minimizes the impact of account compromise and prevents unauthorized data exposure across sensitive application workflows.
