UncleCode Crawl4AI是新加坡UncleCode个人开发者的一款AI驱动的爬虫软件。 UncleCode Crawl4AI 0.9.0之前版本存在安全漏洞，该漏洞源于Docker API服务器接受请求提供的browser_config.extra_args参数，该参数流入Chromium启动参数，攻击者可注入Chromium开关替换子进程启动命令并结合--no-zygote，导致Chromium分叉或执行攻击者控制的命令，从而造成任意命令执行。

Vulnerability Title
Crawl4AI: Unauthenticated RCE via Chromium launch-argument injection in browser_config.extra_args
Source: CVE Program / CVE List V5
Vulnerability Description
Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server accepted request-supplied browser_config.extra_args, which flowed into Chromium's launch arguments. An attacker could inject Chromium switches that replace a child-process launch command together with --no-zygote, causing Chromium to fork or exec an attacker-controlled command as the container's runtime user. The Docker API is unauthenticated by default, so a single request yields arbitrary command execution. This issue is fixed in version 0.9.0.
