Crawl4AI before 0.8.8 contains credential exfiltration vulnerabilities in the Docker API server that allow attackers to redirect LLM API calls to attacker-controlled endpoints and read arbitrary environment variables. Attackers can exploit the unauthenticated /md, /llm, and /llm/job endpoints by supplying a malicious baseurl parameter and setting apitoken to env:VARIABLENAME to exfiltrate provider API keys and server secrets including JWT SECRETKEY for authentication bypass.
