{"id":"GHSA-vx9w-5cx4-9796","summary":"Crawl4AI Has Local File Inclusion in Docker API via file:// URLs","details":"A local file inclusion vulnerability exists in the Crawl4AI Docker API. The /execute_js, /screenshot, /pdf, and /html endpoints accept file:// URLs, allowing attackers to read arbitrary files from the server filesystem.\n\nAttack Vector:\n```json\nPOST /execute_js\n{\n    \"url\": \"file:///etc/passwd\",\n    \"scripts\": [\"document.body.innerText\"]\n}\n```\nImpact\n\nAn unauthenticated attacker can:\n- Read sensitive files (/etc/passwd, /etc/shadow, application configs)\n- Access environment variables via /proc/self/environ\n- Discover internal application structure\n- Potentially read credentials and API keys\n\nWorkarounds\n\n1. Disable the Docker API\n2. Add authentication to the API\n3.
