Description
Crawl4AI before 0.9.5 contains a blind server-side request forgery vulnerability in the Docker server that allows API clients to bypass the egress proxy by enabling check_cache_freshness. Attackers can cache a controlled URL, then trigger CacheValidator to follow 302 redirects or DNS rebinding to internal and cloud-metadata addresses for port and service discovery.
