CVE-2026-26217
Crawl4AI Has Local File Inclusion in Docker API via file:// URLs
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
- Disable the Docker API
- Add authentication to the API
- Use network-level filtering
