If you cannot patch yet, restrict access to the affected endpoints and avoid exposing the Docker API server publicly. Monitor for unusual API call redirections and environment variable access patterns.
Description
Crawl4AI versions before 0.8.8 have credential exfiltration vulnerabilities in their Docker API server. Attackers can exploit unauthenticated endpoints (/md, /llm, /llm/job) by manipulating the base_url parameter and setting api_token to environment variable references, allowing them to read arbitrary environment variables. This can lead to exfiltration of sensitive data such as provider API keys and JWT SECRET_KEY, enabling authentication bypass.
