Short explanation
Crawl4AI before 0.9.5 contains a denial of service vulnerability in the Docker API server due to _clamp_untrusted() failing to cap delay fields in untrusted CrawlerRunConfig bodies.
Unauthenticated attackers can send massive values to /crawl or /crawl/stream endpoints to exhaust the browser page pool and block other crawl operations.
What should be done?
- Update Crawl4AI to version 0.9.5 or later
- Follow official vendor advisories and security guidance

Chain of evidence and sources
Crawl4AI 0.9.5 öncesi sürümler, Docker API sunucusunda _clamp_untrusted() fonksiyonunun CrawlerRunConfig gecikme alanlarını sınırlayamaması nedeniyle hizmet engelleme zafiyeti barındırmaktadır.
Kimliği doğrulanmamış saldırganlar /crawl veya /crawl/stream uç noktalarına büyük değerler göndererek sayfa havuzunu tüketebilir ve tarama işlemlerini bloke edebilir.
Show the technical text from the sources
Crawl4AI before 0.9.5 contains a denial of service vulnerability in the Docker API server where _clamp_untrusted() fails to cap the delay_before_return_html, mean_delay, and max_range fields of untrusted CrawlerRunConfig bodies. Unauthenticated attackers can send huge values to /crawl or /crawl/stream to hold browser pages or stall the rate limiter, exhausting the page pool and blocking other crawls.
