How the CVE Works
CVE-2025-28197 affects Crawl4AI versions <=0.4.247 due to improper input validation in /crawl4ai/async_dispatcher.py. The vulnerability allows attackers to perform SSRF attacks by manipulating HTTP requests, enabling unauthorized access to internal services or sensitive data. The flaw arises when user-supplied URLs are processed without proper sanitization, leading to arbitrary server-side requests. Attackers can exploit this to bypass firewalls, interact with internal APIs, or exfiltrate data from restricted systems.
