漏洞描述
Crawl4AI Docker API server versions before 0.8.7 ship with a hardcoded default JWT signing key ("mysecret") used to sign and verify HS256 authentication tokens. Because the key is identical across every deployment where SECRET_KEY has not been overridden, an unauthenticated attacker can forge a valid Bearer token and use it to access every JWT-protected API endpoint (/md, /html, /screenshot, /pdf, /execute_js, /crawl, /ask).
