Vibe coding is a style of software development where you describe what you want in plain English, let an AI tool generate the code, and ship it — often without fully understanding every line. The term was coined by Andrej Karpathy in February 2025 and named Collins Dictionary's Word of the Year for 2025.

Is vibe coding dangerous?

Vibe coding carries significant security risks when used without proper review processes. Veracode's 2025 report found that 45% of AI-generated code contains security vulnerabilities. A January 2026 benchmark study found that while 61% of AI-generated solutions were functionally correct, only 10.5% were also secure. Real-world incidents including the Lovable platform breach, the Tea App disaster, and the Replit/SaaStr database deletion all demonstrate the real consequences.

What are the most common security vulnerabilities in AI-generated code?

The most common security vulnerabilities in AI-generated code include hardcoded API keys and credentials, SQL injection flaws, broken authentication logic, insecure direct object references (IDOR), insecure data serialisation, and vulnerable third-party dependencies. These vulnerabilities are often invisible in normal use but exploitable by anyone actively looking for them.

How can I use AI coding tools safely?

To use AI coding tools safely: never ship AI-generated code that handles sensitive data without a security review; ask the AI to audit its own code for vulnerabilities after generation; treat AI-generated code like third-party code and read it before shipping; use environment variables instead of hardcoded credentials; integrate automated security scanning (SAST/SCA) into your CI/CD pipeline; and always separate production from development environments.

What happened in the Lovable vibe coding breach?

Security researchers scanned 1,645 live applications built on the Lovable AI app-building platform and found that 170 of them — more than 10% — had critical row-level security flaws in their database configurations, meaning attackers could access real user data including names, emails, financial records, and home addresses. The vulnerability was assigned CVE-2025-48757. Lovable acknowledged it but didn't meaningfully notify affected users for 69 days.

“If an LLM wrote every line of your code, but you’ve reviewed, tested, and understood it – that’s engineering. If you haven’t, that’s gambling.” –…
