OWASP Just Wrote the Security Rulebook for Vibe-Coded Apps — Every No-Code Builder Should Read This

The OWASP Top 10 for 2025 is out, and for the first time, vibe coding is in the conversation. Not as its own category. Tanya Janca, now on the OWASP Top 10 team, told the Stack Overflow podcast the group wanted breach postmortem data on AI-generated code. They couldn't get it, so they flagged it through awareness items instead.

If you build with Bubble, Webflow, Glide, or Stacker, OWASP probably sounds like someone else's problem. It shouldn't be. The same vulnerabilities that wreck vibe-coded apps exist in no-code projects. They just take different shapes. And the numbers are stark: Veracode found that 45% of AI-generated code contains OWASP Top 10 vulnerabilities. Apiiro reported 322% more privilege escalation paths in AI-written code. Escape.tech scanned 5,600 vibe-coded apps and 65% had security issues.

Structured no-code platforms have baked-in defences that raw vibe coding lacks. But those defences only work if you use them.

The categories that hit closest to home

Three OWASP categories matter most for no-code builders: A01 Broken Access Control, A02 Security Misconfiguration, and A03 Software Supply Chain Failures. The rest — injection, authentication failures, cryptographic weaknesses — are mostly handled by the platform. You won't be writing SQL queries in Bubble, and Webflow isn't going to let you accidentally ship an app with DEBUG=True.

But access control? Misconfiguration? Supply chain? Those are yours to manage.

What broken access control looks like in Bubble

A01 has sat at number one for two editions. In traditional development, it means putting auth checks in the browser instead of the server, or letting anyone reach /admin by guessing the URL. In Bubble, the equivalent is privacy rules that aren't set.

Bubble's privacy rules engine controls which users see which data at the database level. It's server-side. You can't bypass it by fiddling with URLs or browser dev tools. But it only works if you configure it.

I've seen apps where every data type was set to "Everyone" because the builder didn't want to deal with permissions during prototyping, then forgot to lock things down before launch. That's A01 in no-code form. Your user records, your payment history, your internal notes — all visible to anyone who knows the API endpoint.

The fix is simple. For every data type, ask: who should see this? Then set privacy rules that answer that question. "This user's own orders." "Admins only." "Logged-in users in the same organisation." Bubble's rule builder makes this straightforward. The hard part is remembering to do it.

Security misconfiguration: where the platform protects you

A02 jumped from number five to number two in the 2025 edition. In vibe-coded apps, this looks like CORS set to *, debug mode left on, no rate limiting, S3 buckets open to the internet. The OWASP documentation notes that 100% of tested applications had some form of misconfiguration.

Structured no-code platforms handle most of this at the infrastructure level. Bubble is SOC 2 Type II compliant. Webflow manages TLS, headers, and CDN configuration. Stacker handles authentication and data-layer access control out of the box. You don't need to think about whether your encryption is configured correctly, because someone already did.

But there are still things you can get wrong. Publishing a page that should be behind login. Embedding an API key in a visible workflow. Leaving a test user with admin privileges in your user database. These are no-code misconfigurations, and they happen constantly.

Supply chain: the AI hallucination problem

A03 is the big new category for 2025. It expands the old "vulnerable and outdated components" to cover the entire toolchain. Tanya Janca explained the shift: your IDE, your CI pipeline, your code repository — every link matters.

For vibe coders, this is existential. AI models hallucinate package names. Simon Roses documented cases where LLMs import dependencies that don't exist, which attackers then register as malicious packages. If your AI assistant invents react-auth-validator and someone claims that namespace on npm, your app now runs attacker-controlled code.

No-code platforms avoid this almost entirely. You're not importing npm packages. You're using platform-native plugins and integrations, which are curated. Bubble's plugin marketplace vets submissions. Webflow's integrations go through review. The supply chain is shorter and simpler.

The trade-off is that you depend on the platform. If Bubble has a security incident, your app is affected. That's a different kind of risk from having a thousand invisible dependencies in your node_modules folder.

Your no-code security checklist

Five things every no-code builder should do this week. They take about an hour total.

1. Audit your privacy rules. Go through every data type in your Bubble app (or the equivalent in your platform) and verify that access controls are set. "Everyone" should be the exception, not the default.

2. Check your published pages. Is anything live that should be behind authentication? In Webflow, verify your membership-gated pages are actually gated. In Glide, check your visibility settings.

3. Rotate your API keys. If you've embedded API tokens in workflows or front-end elements, move them to environment variables or secrets management. If your platform doesn't offer that, find one that does.

4. Remove test accounts and debug data. That test@test.com account with full admin access? Delete it. Sample data you imported during onboarding? Gone. Production environments should be clean.

5. Review your integrations. For every plugin, API connector, and third-party integration in your app, check: do I still need this? Is it still maintained? If the answer to either is no, remove it.

The takeaway

The OWASP Top 10 isn't just for traditional developers any more. The 2025 edition, with its supply chain expansion and vibe coding awareness items, is a document every no-code builder should read. At minimum, the summaries for A01, A02, and A03.

Structured no-code platforms give you a security head start that raw vibe coding doesn't. Privacy rules, managed authentication, curated plugins, platform-level encryption. These things are real and they matter. But they're defaults that need configuring, not a licence to stop thinking about security. The checklist above takes an hour. Do it this week.
