Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-26217. PoCs published by dwisiswant0.

AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-26217, demonstrating unauthenticated local file inclusion (LFI) in Crawl4AI versions prior to 0.8.0 via the Docker API endpoints. The exploit leverages the `file://` URL scheme to read arbitrary files from the server filesystem.

Description

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.
