eslint-plugin-vercel-ai-security

⭐ If this plugin caught a real bug for you, star the repo — it's the signal that keeps these rules maintained.

Description

This plugin provides Security rules for Vercel AI SDK usage (prompt injection, data handling).

• Why — a linter nobody reads protects nothing. We would rather miss a finding than spend your attention on one that was never real.
• How — evidence, not names. A rule fires on what the code does, resolved through the AST and ESLint's own scope analysis.
• What — every finding carries its fix, in prose for a human and as structured JSON for an agent. Security rules add a CWE mapping and, where assigned, a CVSS score.

That trade costs recall, and we measure it: methodology · results · a false positive is a bug.

Getting Started

• To check out the guide, visit eslint.interlace.tools. 📚

npm install eslint-plugin-vercel-ai-security --save-dev

ai (Vercel AI SDK)			Prompt Injection, Data Leakage

🤖 AI-Agent Optimized Messages

All rule messages follow a structured format optimized for AI coding assistants:

🔒 CWE-74 OWASP:A03-Injection CVSS:9 | Unsafe Prompt | CRITICAL [SOC2,GDPR]
   Fix: Validate input before use | https://owasp.org/...

By providing this structured context (CWE, OWASP, Fix), we enable AI tools to reason about the security flaw rather than hallucinating. This allows Copilot/Cursor to suggest the exact correct fix immediately.

🙋 FAQ

What's the difference between this and generic AI security linters?

Generic linters guess at patterns. This plugin knows the exact Vercel AI SDK API.

Does this work with ESLint 9 Flat Config?

Yes! Designed specifically for ESLint Flat Config — works on ESLint 8 (with flat config), 9, and 10. See the ESLint Version Support Policy for the full matrix.

How do I suppress a rule for a specific line?

// eslint-disable-next-line vercel-ai-security/require-validated-prompt
await generateText({ prompt: internalPrompt });

Why is ASI06 (Memory Corruption) not covered?

TypeScript/JavaScript are memory-safe languages. Memory corruption vulnerabilities (buffer overflows, use-after-free, etc.) are not possible in these environments.
