要点
- CVE-2026-26217 は crawl4ai, crawl4ai (kidocode) に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：2.1%（全脆弱性の 81.7% より高い）。
- 対処：0.8.0 以降に更新してください。
概要
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
NVD の説明
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.
