CVE-2026-26217

Crawl4AI < 0.8.0 Docker API Local File Inclusion via file URL Handling

State: Published
Severity: 9.2 Critical
Published: Feb 12, 2026
Updated: Oct 8, 2026
Reserved: Feb 11, 2026

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.
