⚠️ Vibe coding is powerful. It can also be dangerous if you don’t know what the agent is doing under the hood.
A real case says it all: Moltbook, an AI social network, suffered a massive leak from vibe coding — 1.5 million API keys and 35,000 emails exposed. The cause: shortcuts that coding agents took without considering security.
Why do agents fail at security?
Speed over safety: LLMs optimize for making code run, not making it safe. If there’s an error, the agent “resolves” it even if it means disabling validations.
No full context awareness: when refactoring one file, the agent can break security controls in another file it wasn’t looking at.
Pattern matching, not judgment: to an agent, a security check is just another bug preventing the code from executing.
3 real security bugs generated by vibe coding:
❌ Exposed API Keys → the agent puts the key directly in frontend JS (visible in “Inspect Element”)
❌ Public database → to resolve “Permission Denied” in Supabase, adds USING (true) → entire DB becomes public
❌ XSS vulnerabilities → to render HTML, uses dangerouslySetInnerHTML without sanitizing
💡 Explanation in a nutshell#
Coding agents are excellent at quickly generating business logic, but have a critical blind spot: they don’t understand the security implications of what they write. The solution isn’t to stop using them, but to actively review them and add security review layers to the development process.
