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 0.8.7之前版本存在安全漏洞,该漏洞源于_safe_eval_expression()函数中的AST验证器仅阻止以下划线开头的属性,导致可以通过Python生成器和帧对象属性实现沙箱逃逸,造成任意代码执行。

|---|---|---|---|
| 1 | Crawl4AI through 0.8.6 ships a Docker API server that exposes an unauthenticated /crawl endpoint. The computed field type of JsonCssExtractionStrategy evaluates a user supplied expression inside an AST based sandbox that does not restrict attribute access on generator frame objects. A generator expression can therefore reach gi_frame.f_back, walk the caller chain to f_builtins, recover __import__ and execute arbitrary operating system commands as the user running the container. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-53753.yaml | POC详情 |
