IS CLAUDE SAFE?

Claude may generate code that calls API methods, library functions, or endpoints that do not actually exist. If these hallucinated calls fail silently or return unexpected values, they can create logic bugs that bypass security checks or crash your application.

Generated code often focuses on the happy path without proper try-catch blocks or error boundaries. Unhandled errors in production expose stack traces, file paths, database connection strings, and internal architecture details to attackers.

Claude-generated form handlers and API mutations frequently omit CSRF token validation. Without CSRF protection, attackers can craft malicious pages that trick authenticated users into performing unintended actions on your application.

Claude often includes placeholder API keys, database URLs, and secret tokens in generated code examples. If these placeholders are not replaced or are accidentally committed to version control, they become real attack vectors or expose your development patterns.

Generated form validation code frequently runs only in the browser with no server-side counterpart. Attackers bypass all client-side checks by sending requests directly to your API, submitting any data they want without restriction.

Does Claude-generated code have security vulnerabilities?

It can. While Claude produces generally well-structured code, it can hallucinate APIs, skip error handling, omit CSRF protection, and include example secrets. Every piece of generated code should be reviewed for security before deployment. UNPWNED scans your live application to catch vulnerabilities that survive code review.

What does API hallucination mean and why is it dangerous?

API hallucination is when Claude generates code that calls functions or endpoints that do not exist. If your code tries to call a non-existent security middleware or validation function, the security check silently fails and your application runs without protection. UNPWNED detects the downstream effects like missing headers and exposed endpoints.

How do I prevent example secrets from leaking into production?

Use environment variables for all secrets and add a pre-commit hook that scans for hardcoded keys and tokens. Never accept placeholder values like sk-example-key or your-api-key-here in committed code. UNPWNED scans for exposed secrets, API keys, and configuration files in your deployed application.

Why does Claude skip server-side validation?

When asked to build a form, Claude often focuses on the user experience and generates client-side validation for immediate feedback. Server-side validation is a separate concern that must be explicitly requested or added during review. UNPWNED tests your API endpoints directly and detects when server-side validation is missing.

Is Claude-generated code safer than ChatGPT-generated code?

Both AI assistants can produce code with security issues, though the specific patterns differ. The safest approach is to review all AI-generated code regardless of source and scan your deployed application with UNPWNED. Automated scanning catches vulnerabilities that even experienced developers miss during manual review.
