HighCVSS 7.5/10Last modified Nov 4, 2026

Description

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.
