OpenAI Codex Security

Skill by ara.so — Security Skills collection

OpenAI Codex Security is an AI-powered CLI and TypeScript SDK that finds, validates, and fixes security vulnerabilities in your codebase. It leverages OpenAI's models to perform intelligent code scanning, vulnerability detection, and automated security remediation.

Installation

Requires Node.js 22.13.0+ (22.x), 24.x, or 26.x; Python 3.10+; and access to Codex Security.

npm install @openai/codex-security

For global CLI access:

npm install -g @openai/codex-security

Authentication

Interactive Login (Local Development)

npx @openai/codex-security login

This stores credentials in Codex's credential home or system keyring for persistent access.

API Key (CI/CD)

Set environment variables instead of interactive login:

export OPENAI_API_KEY=your_key_here
# or
export CODEX_API_KEY=your_key_here

Environment API keys take precedence in non-interactive environments and are never persisted.

Credential Selection

If both ChatGPT sign-in and API key are available:

# Use ChatGPT credentials
npx @openai/codex-security scan . --auth chatgpt

# Use API key
npx @openai/codex-security scan . --auth api-key

To make ChatGPT sign-in the default:

unset OPENAI_API_KEY CODEX_API_KEY

CLI Commands

Basic Scan

Scan current directory:

npx @openai/codex-security scan .

Scan specific directory:

npx @openai/codex-security scan /path/to/project

Advanced Scanning Options

Use specific model with higher effort:

npx @openai/codex-security scan . --model gpt-5.6-terra --effort high

Available effort levels:

• low - Quick scan, fewer checks
• medium - Balanced (default)
• high - Thorough scan, maximum coverage

Scan Output

Scan history is stored in the Codex Security workbench state directory. If the directory is not writable, configure an alternative:

export CODEX_SECURITY_STATE_DIR=/path/to/writable/dir
npx @openai/codex-security scan .

TypeScript SDK

Basic Usage

import { CodexSecurity } from "@openai/codex-security";

const security = new CodexSecurity();
const result = await security.run(".");

console.log(`Scan complete. Report: ${result.reportPath}`);
console.log(`Vulnerabilities found: ${result.vulnerabilities.length}`);

await security.close();

Scan with Options

import { CodexSecurity } from "@openai/codex-security";

const security = new CodexSecurity({
  model: "gpt-5.6-terra",
  effort: "high",
  auth: "api-key"
});

const result = await security.run("/path/to/project");

// Process vulnerabilities
for (const vuln of result.vulnerabilities) {
  console.log(`${vuln.severity}: ${vuln.title}`);
  console.log(`  File: ${vuln.file}:${vuln.line}`);
  console.log(`  Description: ${vuln.description}`);
}

await security.close();

Scan Specific Files

import { CodexSecurity } from "@openai/codex-security";

const security = new CodexSecurity();

const result = await security.run(".", {
  files: [
    "src/auth.ts",
    "src/api/users.ts",
    "lib/db.ts"
  ]
});

console.log(`Scanned ${result.filesScanned} files`);
await security.close();

Using Environment Variables for Authentication

import { CodexSecurity } from "@openai/codex-security";

// Ensure OPENAI_API_KEY or CODEX_API_KEY is set
if (!process.env.OPENAI_API_KEY && !process.env.CODEX_API_KEY) {
  throw new Error("API key required");
}

const security = new CodexSecurity({
  auth: "api-key"
});

const result = await security.run(".");
await security.close();

Handling Scan Results

import { CodexSecurity } from "@openai/codex-security";
import fs from "fs/promises";

const security = new CodexSecurity();
const result = await security.run(".");

// Filter by severity
const critical = result.vulnerabilities.filter(v => v.severity === "critical");
const high = result.vulnerabilities.filter(v => v.severity === "high");

console.log(`Critical: ${critical.length}, High: ${high.length}`);

// Export to JSON
await fs.writeFile(
  "security-report.json",
  JSON.stringify(result, null, 2)
);

// Check if scan passed
if (result.vulnerabilities.length === 0) {
  console.log("✅ No vulnerabilities found");
} else {
  .();
  process.();
}

 security.();

Common Patterns

Pre-commit Hook

Create .husky/pre-commit:

#!/bin/sh
npx @openai/codex-security scan . --effort low --auth chatgpt

Integration with Testing

import { CodexSecurity } from "@openai/codex-security";
import { describe, it, expect, afterAll } from "@jest/globals";

describe("Security Checks", () => {
  const security = new CodexSecurity();

  afterAll(async () => {
    await security.close();
  });

  it("should have no critical vulnerabilities", async () => {
    const result = await security.run(".");
    const critical = result.vulnerabilities.filter(
      v => v.severity === "critical"
    );
    
    expect(critical).toHaveLength(0);
  }, 300000); // 5 min timeout

  it("should have no high severity SQL injection issues", async () => {
    const result = await security.run(".");
    const sqlInjection = result.vulnerabilities.filter(
      v => v.type.() && v. === 
    );
    
    (sqlInjection).();
  }, );
});

Automated Fix Workflow

import { CodexSecurity } from "@openai/codex-security";
import { exec } from "child_process";
import { promisify } from "util";

const execAsync = promisify(exec);
const security = new CodexSecurity({ model: "gpt-5.6-terra" });

async function scanAndFix() {
  console.log("Running security scan...");
  const result = await security.run(".");
  
  if (result.fixableVulnerabilities > 0) {
    console.log(`Found ${result.fixableVulnerabilities} auto-fixable issues`);
    
    // Apply fixes (hypothetical API)
    // await security.fix(result);
    
    // Verify fixes with another scan
    const verifyResult = await security.run(".");
    console.log(`Remaining issues: ${verifyResult.vulnerabilities.length}`);
  }
  
  await security.close();
}

scanAndFix().(.);

Environment Variables

• OPENAI_API_KEY - OpenAI API key for authentication
• CODEX_API_KEY - Alternative API key variable
• CODEX_SECURITY_STATE_DIR - Custom directory for scan history (default: system-specific state directory)

Troubleshooting

Node.js Version Issues

Ensure you're using a compatible Node.js version:

node --version  # Should be 22.13.0+, 24.x, or 26.x

Use nvm to switch versions:

nvm install 22
nvm use 22

Python Not Found

Install Python 3.10 or later:

# Ubuntu/Debian
sudo apt-get install python3.10

# macOS
brew install python@3.10

# Verify
python3 --version

Credential Issues

If credentials aren't persisting:

# Check current credentials
npx @openai/codex-security login --status

# Re-login
npx @openai/codex-security logout
npx @openai/codex-security login

For CI environments, always use environment variables instead of login.

State Directory Not Writable

Set a custom state directory:

export CODEX_SECURITY_STATE_DIR="${HOME}/.codex-security-state"
mkdir -p "${CODEX_SECURITY_STATE_DIR}"
npx @openai/codex-security scan .

Scan Timeout

For large codebases, increase effort level or scan specific directories:

# Lower effort for faster scans
npx @openai/codex-security scan . --effort low

# Scan specific subdirectories
npx @openai/codex-security scan ./src

API Rate Limits

If you encounter rate limits, consider:

1. Reducing scan frequency
2. Using lower effort levels
3. Scanning only changed files in CI
4. Requesting higher rate limits from OpenAI

Access Denied

Ensure your account has access to Codex Security. For best results, verify your account for Trusted Access.
