Credential exfiltration via attacker-controlled LLM endpoint
Published Jul 12, 2026 · Updated Jul 12, 2026
Credential exposure in Crawl4AI before 0.8.8 allows remote attackers to steal server secrets through unauthenticated Docker API endpoints. The /md, /llm, and /llm/job handlers honor a request-supplied base_url while attaching configured provider keys, and LLMConfig resolves env:-prefixed api_token values through os.getenv. Default Docker API deployments require no authentication, enabling disclosure of provider keys or JWT SECRET_KEY and subsequent authentication bypass.
Summary
What happened
Credential exposure in Crawl4AI before 0.8.8 allows remote attackers to steal server secrets through unauthenticated Docker API endpoints. The /md, /llm, and /llm/job handlers honor a request-supplied base_url while attaching configured provider keys, and LLMConfig resolves env:-prefixed api_token values through os.getenv. Default Docker API deployments require no authentication, enabling disclosure of provider keys or JWT SECRET_KEY and subsequent authentication bypass.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
