PYSEC-2026-34

Vulnerability from pysec - Published: 2026-02-12 16:16 - Updated: 2026-05-20 09:18

Details

Crawl4AI versions prior to 0.8.0 contain a local file inclusion vulnerability in the Docker API deployment. The /execute_js, /screenshot, /pdf, and /html endpoints accept file:// URLs, allowing unauthenticated remote attackers to read arbitrary files from the server filesystem. An attacker can access sensitive files such as /etc/passwd, /etc/shadow, application configuration files, and environment variables via /proc/self/environ, potentially exposing credentials, API keys, and internal application structure.

Severity

7.5 (High)

GHSA-VX9W-5CX4-9796

Vulnerability from github – Published: 2026-01-16 20:58 – Updated: 2026-06-05 14:44

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

Disable the Docker API
Add authentication to the API
Use network-level filtering

Severity

8.6 (High)
