Vibe coding does not remove security work. It moves security earlier, because a founder can now ship risky code faster than they can understand it. Use this checklist before a product touches users, payments, private data, or production systems.
Secrets
No API key, database URL, webhook signing secret, private token, or service credential belongs in source code. Store secrets in local environment files and deployment settings. Ask the agent to reference environment variables by name, not by value.
Run a secret scan before deploy and inspect new files manually. Generated content, docs, screenshots, and logs can leak secrets too.
Auth and permissions
Authentication is not just login. Check session expiry, protected routes, server-side authorization, profile updates, and user-specific data access. A UI guard is not enough if the API route still returns data.
For every sensitive route, ask: who can call this, how do we know, and what happens when they should not?
Payments
Payment code needs webhook verification, server-side price checks, clear success and failure states, and no client-side trust for subscription status. Do not let an agent invent checkout logic from memory when official SDK docs exist.
Test failure paths. A founder who only tests the happy path is not done.
Prompt injection and untrusted content
If your product asks an agent to read user uploads, URLs, emails, issues, READMEs, or web pages, treat that content as untrusted. The content may contain instructions that try to redirect the agent, leak data, or perform unwanted actions.
Separate data from instructions. Tell the agent which sources are untrusted and forbid external actions based solely on those sources.
Logs, dependencies, and release proof
Logs should help debug without storing sensitive payloads. Dependencies should be audited for known issues. Release proof should separate local build success from hosted behavior and payment readiness.
The checklist is simple: scan, build, smoke test, review changed files, verify routes, then deploy. If the product handles money or private data, add a human security review.

FAQ
Is vibe-coded software insecure by default? No, but it is easy to ship insecure software quickly. Security depends on review, official patterns, testing, and not trusting generated code blindly.
What is the first security check I should run? Scan for secrets and inspect auth-protected data access. Secret leaks and broken authorization are common high-impact launch risks.
Should I let AI agents read user uploads? Only with clear boundaries. Treat uploads as untrusted data, not instructions, and restrict what the agent can do after reading them.
