Crawl4AI from 0.8.7 through 0.9.5 contains a server-side request forgery vulnerability in the Docker API server that allows unauthenticated attackers to bypass destination checks via URL userinfo parsing differences. Attackers can set fetch_ssl_certificate=true with crafted userinfo URLs so SSLCertificate.from_url connects to internal hosts on port 443, probing reachability and leaking certificate details.
