🛡️ Sentinel: [CRITICAL] Fix command injection risks by replacing execSync with execFileSync in system-status.ts

[bobdivx]

🚨 Severity: CRITICAL
💡 Vulnerability: Use of execSync with shell execution could lead to command injection vulnerabilities.
🎯 Impact: An attacker could potentially inject arbitrary shell commands.
🔧 Fix: Replaced execSync with execFileSync to avoid shell execution and pass arguments directly. Also added fallback logic without using shell operators.
✅ Verification: Ran pnpm run check and pnpm test to ensure no regressions.

Code Review

This pull request replaces execSync with execFileSync in src/pages/api/system-status.ts to mitigate command injection risks when executing df and docker ps commands, and documents this security practice in .jules/sentinel.md. The review feedback recommends adding a timeout option to these synchronous execFileSync calls to prevent blocking the Node.js event loop indefinitely if the underlying commands hang.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Since execFileSync is a synchronous operation, if the df command hangs (e.g., due to a hung network mount or disk issues), it will block the entire Node.js event loop indefinitely. This prevents the server from handling any other incoming requests. Adding a timeout option ensures the command fails gracefully if it takes too long.

Suggested change

	dfOutput = execFileSync('df', ['-P', targetPath]).toString();
	} catch {
	try {
	dfOutput = execFileSync('df', ['-P', '/']).toString();
	} catch {
	dfOutput = '';
	}
	dfOutput = execFileSync('df', ['-P', targetPath], { timeout: 2000 }).toString();
	} catch {
	try {
	dfOutput = execFileSync('df', ['-P', '/'], { timeout: 2000 }).toString();
	} catch {
	dfOutput = '';
	}

Similarly, docker ps can hang if the Docker daemon is unresponsive or under heavy load. Since this is a synchronous call in an API route, it will block the Node.js event loop. Adding a timeout option is highly recommended to prevent potential Denial of Service (DoS) of the API.

Suggested change

	const unhealthy = execFileSync('docker', ['ps', '--filter', 'health=unhealthy', '--format', '{{.Names}}']).toString();
	const unhealthy = execFileSync('docker', ['ps', '--filter', 'health=unhealthy', '--format', '{{.Names}}'], { timeout: 5000 }).toString();
