AI coding tools build working software fast, but security flaws inevitably arise during vibe coding. Here is how to identify them, fix them, and protect user data.
When developers build applications with AI coding tools (Cursor, Claude Code, Lovable, Bolt, v0, Windsurf), the AI focuses on generating code that immediately works for the prompt. However, standard LLM outputs routinely cut corners on defensive engineering:
AI hides buttons or disables UI inputs for non-admins, but leaves the underlying backend API routes completely unprotected.
AI accepts pricing, quantities, discounts, or account roles directly from the client JSON body rather than verifying server-side.
Database tables are created without strict RLS policies, allowing any authenticated user to dump or modify records belonging to others.
Endpoints that invoke paid LLMs (OpenAI, Anthropic) or send OTP SMS messages are created without rate limiting or abuse controls.
ShipSecurely provides the antidote: a structured checklist with ready-to-paste prompts so you can hand the audit and remediation tasks straight back to your AI agent before launching.
Essential rules for securing data that users give to your app or website.
When users trust your app with their email addresses, billing information, private messages, or documents, data protection cannot be an afterthought. Apply these fundamental data security practices:
Always scope database queries to the requesting user’s session ID (e.g. WHERE id = :id AND user_id = :currentUserId). Never rely solely on object IDs in URLs.
Store auth tokens exclusively in httpOnly, Secure cookies for web apps, and iOS Keychain / Android Keystore for mobile apps. Never store tokens in plaintext localStorage.
Validate every incoming user payload against strict runtime schemas (Zod). Strip unexpected keys to prevent mass assignment, and sanitize form inputs to prevent XSS and injection attacks.
Never print user passwords, tokens, or PII into server console logs or mobile device logs. Strip stack traces from production error responses to prevent information disclosure.
