Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Crawl4AI versions before 0.8.8 have a flaw in the Docker API server that lets a request control the LLM endpoint and which server environment variable an LLM token resolves from. An unauthenticated attacker, who can reach the Docker API (which is unauthenticated by default), can send requests that leak the server's LLM provider API key and other secrets, such as a JWT signing key, to an endpoint they control. Upgrade to crawl4ai 0.8.8 or later. Enabling authentication with CRAWL4AI_API_TOKEN is also a listed workaround.
