CVE-2026-57573: Kidocode CRAWL4AI

High severity, CVSS 8.6. EPSS: 0.4% chance of exploitation in the next 30 days.

Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server applied its SSRF destination check on the non-streaming /crawl path but not on the streaming path. handle_stream_crawl_request passed seed URLs straight to the crawler with no destination validation, allowing a remote unauthenticated client to call POST /crawl/stream or POST /crawl with crawler_config.stream=true with a URL pointing at an internal, private, or link-local address; the server fetched it and streamed the response body back. This issue is fixed in version 0.9.0.

Affected products

• Kidocode CRAWL4AI: before 0.9.0 (fixed in 0.9.0)
