  • 8.8 (High) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N CVSS Calculator
Summary
Crawl4AI - LLM Credential Exfiltration via base_url and Environment Variable Resolution
Details

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.
