Summary
Crawl4AI Has Local File Inclusion in Docker API via file:// URLs
Details

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 keys

Workarounds

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