The OWASP LLM Protocol: 100% Automated Coverage for Vercel AI

Governance for AI agents is the new frontier for CTOs. Here is the engineering standard for mapping the Vercel AI SDK to the OWASP LLM Top 10 through 100% automated static analysis rules.

The OWASP LLM Top 10 2025 is here. And your Vercel AI SDK application probably violates half of it.

I know because I built a plugin to check. One ESLint config. Full OWASP coverage. 60 seconds to install.

This plugin is designed specifically for the Vercel AI SDK. It understands generateText, streamText, tool(), and other SDK functions—not just pattern-matching on strings.

The 10 Categories (And How to Automate Them)

# OWASP Category What It Means ESLint Rule
LLM01 Prompt Injection User input manipulates AI behavior require-validated-prompt
LLM02 Sensitive Information Disclosure Secrets/PII leaked to LLM no-sensitive-in-prompt
LLM03 Supply Chain Vulnerabilities Compromised models/libraries no-training-data-exposure
LLM04 Data and Model Poisoning Malicious data in fine-tuning require-request-timeout
LLM05 Improper Output Handling AI output executed as code no-unsafe-output-handling
LLM06 Excessive Agency AI invokes tools without consent require-tool-confirmation
LLM07 System Prompt Leakage AI reveals system instructions no-system-prompt-leak
LLM08 Vector and Embedding Weaknesses Malicious embeddings in RAG require-embedding-validation
LLM09 Misinformation AI output displayed without checks require-output-validation
LLM10 Unbounded Consumption Token/step exhaustion require-max-tokens, require-max-steps

Why This Matters

OWASP isn't just a checklist for security audits. It's becoming a compliance requirement.

If you're building AI features for enterprise customers, they will ask: "How do you address the OWASP LLM Top 10?"

Having an automated, auditable answer makes the difference between a closed deal and a 6-month security review.

Before & After

Before (silent vulnerability):

await generateText({
  prompt: userInput, // No validation, no warning
});
Enter fullscreen mode Exit fullscreen mode

After (with the linter):

🔒 CWE-74 OWASP:LLM01 CVSS:9.0 | Unvalidated prompt input | CRITICAL
   Fix: Validate/sanitize user input before use
Enter fullscreen mode Exit fullscreen mode

No more finding these in production.

The Implementation

eslint-plugin-vercel-ai-security provides SDK-aware rules for the Vercel AI SDK. It's not pattern-matching on strings—it understands generateText, streamText, tool(), and other SDK functions.

// eslint.config.js
import vercelAISecurity from "eslint-plugin-vercel-ai-security";

export default [
  vercelAISecurity.configs.recommended, // Balanced security
  // vercelAISecurity.configs.strict,   // Maximum security
];
Enter fullscreen mode Exit fullscreen mode

CI Integration

Every PR now gets automatic OWASP validation:

# .github/workflows/security.yml
- name: Lint AI Security
  run: npx eslint 'src/**/*.ts' --max-warnings 0
Enter fullscreen mode Exit fullscreen mode

The Punch Line

100% OWASP LLM coverage sounds impressive in a sales deck. But more importantly, it means your AI application is protected against the most common attack patterns.

The plugin is free. The compliance is automatic. The alternative is manual pen-testing at $500/hour.

Your call.
