GHSA-vx9w-5cx4-9796: 
Python vulnerability analysis and mitigation

A local file inclusion vulnerability exists in the Crawl4AI Docker API. The /execute_js, /screenshot, /pdf, and /html endpoints accept file:// URLs, allowing attackers to read arbitrary files from the server filesystem. Attack Vector:

POST /execute_js
{
    "url": "file:///etc/passwd",
    "scripts": ["document.body.innerText"]
}

Impact An unauthenticated attacker can:

• Read sensitive files (/etc/passwd, /etc/shadow, application configs)
• Access environment variables via /proc/self/environ
• Discover internal application structure
• Potentially read credentials and API keysWorkarounds

1. Disable the Docker API
2. Add authentication to the API
3. Use network-level filtering
