Vibe-coded apps, built quickly with AI tools, tend to ship the same handful of security problems, so scanning for them before launch is worth building into your process. The things to scan for are hardcoded secrets, missing backend access controls like Row Level Security, over-broad permissions, insecure network configuration including missing security headers, and vulnerable dependencies. No single tool covers all of it, so a practical setup combines a mobile app build scanner, a secret scanner, a backend or database check, a security-headers check, and a dependency scanner. What matters is that each category is covered, because AI-generated apps rarely secure any of them by default.
Short answer
Scan a vibe-coded app across five areas, using a different tool for each, since none covers everything. Check the compiled app for secrets, insecure storage, over-broad permissions, and weak network settings, mapped to the OWASP Mobile Application Security standard. Scan the source for hardcoded keys with a secret scanner. Verify the backend, especially that Row Level Security is enabled on every table. Check web security headers like HSTS and a content security policy. And scan dependencies for known vulnerabilities. The two most commonly missed in AI-built apps are backend RLS and security headers, so make sure those are explicitly covered rather than assumed.
Why vibe-coded apps need scanning
Apps built rapidly with AI assistance optimize for working, not for secure, and the two are different goals. An AI tool will happily produce an app that runs while leaving out the controls that a security-minded developer would add, because those controls are not required for the demo to function. The result is a predictable set of gaps that recur across many generated apps.
This is why a scan is not optional for these projects. The same speed that makes vibe coding attractive is what skips the security steps, so the review has to happen after the fact, before the app holds real user data. Treating a generated app as needing a security pass, rather than trusting that it is safe because it happens to work in a demo, is the mindset that catches these issues before users do.
What to scan for
The high-value targets are consistent across vibe-coded apps. Hardcoded secrets come first, since AI tools readily inline API keys or database credentials that then ship in the app or the repository. Missing backend access controls are next, most importantly a database without Row Level Security, which can expose all its data through a public key. Over-broad permissions follow, where the app requests access it cannot justify.
The remaining two are network and dependencies. Insecure network configuration includes cleartext traffic and missing security headers on any web surface, which undermine the transport security the app relies on. Vulnerable dependencies round it out, since a generated app can pull in packages with known flaws. Scanning for these five, secrets, backend access, permissions, network, and dependencies, covers the great majority of what actually goes wrong.
RLS and security headers
Two items deserve special attention because they are both high-impact and frequently missed. Row Level Security is the database control that decides what a public client key can read or write, and a vibe-coded backend often ships without it, which turns the intentionally public key into full access to your data. Verify that RLS is enabled on every client-reachable table and that its policies actually restrict access, testing as the anonymous role.
Security headers are the web equivalent, a set of HTTP response headers that harden the browser side. Missing headers like Strict-Transport-Security, a content security policy, and clickjacking protection leave common attacks open even when the rest of the app is fine. Check them with a headers scanner, and add the ones that are absent. Because RLS and headers are configuration rather than visible features, they are easy to overlook, which is exactly why they top the list of things to confirm explicitly.
Categories of security scanners
No single scanner covers a whole app, so think in categories and cover each one. A mobile app build scanner inspects the compiled artifact for secrets, insecure storage, permissions, and network settings. A secret scanner reads your source and history for hardcoded keys. A backend or database check confirms access controls like RLS. A web security-headers scanner checks the browser-facing configuration. And a dependency scanner flags packages with known vulnerabilities.
Each category has good tools, including open-source ones. For source secrets, scanners such as gitleaks are widely used. For the backend, a service like Supabase provides advisors that flag tables missing RLS, alongside manual review. For dependencies, package-audit tooling and services catch known issues. The point is not any single product but coverage: pick a tool for each category so nothing important goes unchecked.
Mobile app build scanning
For the compiled app itself, a build scanner is the tool that sees what actually shipped, including secrets and misconfigurations that source review can miss. The open-source Mobile Security Framework, MobSF, is a well-known option that analyzes an app package and reports findings. A scanner like PTKD.com does the same with findings ordered by severity and mapped to OWASP MASVS, which makes it straightforward to see which controls a vibe-coded app is missing and how serious each gap is.
The value of scanning the build, rather than only the source, is that it reflects reality: it catches a key that was inlined despite your intentions, a permission the final app requests, or an insecure network setting that made it into the artifact. To be clear about the boundary, a build scanner checks the app you ship; it does not configure your backend RLS or add your web security headers, which are separate categories you still cover with their own checks.
Scanner categories compared
Seeing the categories together makes it easy to assemble coverage. The table below maps each to example tools and what it catches.
| Category | Example tools | What it catches |
|---|---|---|
| Mobile app build | MobSF, PTKD.com | Secrets, insecure storage, permissions, network |
| Secrets in code | gitleaks, other secret scanners | Hardcoded keys and credentials |
| Backend and RLS | Supabase advisors, manual review | Missing Row Level Security, open tables |
| Web security headers | Header scanners, DAST tools | Missing HSTS, CSP, clickjacking protection |
| Dependencies | Package-audit tools and services | Known-vulnerable packages |
Read the table as a coverage map rather than a ranking. The goal is one tool per row, so that secrets, the app build, the backend, the web headers, and the dependencies are all checked, since a vibe-coded app can fail in any of them.
What to scan checklist
A concrete checklist turns the categories into a pre-launch routine. The list below covers the essentials.
| Check | What to look for | Done? |
|---|---|---|
| Secrets | No hardcoded keys in the code, history, or build | [ ] |
| Backend RLS | Row Level Security on every table, tested as anon | [ ] |
| Permissions | No permissions the app cannot justify | [ ] |
| Network and headers | HTTPS everywhere, HSTS and CSP present, no cleartext | [ ] |
| Dependencies | No packages with known vulnerabilities | [ ] |
The two rows people skip are backend RLS and network headers, which is exactly why they are so often the source of a vibe-coded app's exposure. Run each check before launch, and re-run them when you add features, since a new screen or dependency can reintroduce a gap you already closed.
What to take away
- Vibe-coded apps ship a predictable set of security gaps, so scanning for them before launch should be part of the process, not an afterthought.
- Scan for five things: hardcoded secrets, missing backend access controls, over-broad permissions, insecure network and headers, and vulnerable dependencies.
- Row Level Security and web security headers are the two most commonly missed, so confirm them explicitly rather than assuming they are present.
- No single tool covers everything; combine a build scanner, a secret scanner, a backend check, a headers scanner, and a dependency scanner.
- For the compiled app, a build scanner like PTKD.com maps findings to OWASP MASVS, while separate tools cover the backend and web layers.
