Summary
Crawl4AI before version 0.8.7 has an arbitrary file write vulnerability in the /screenshot and /pdf endpoints of the Docker API server. The output_path parameter accepts arbitrary filesystem paths without validation, allowing an attacker to overwrite server files and cause denial of service.

Recommendation
Immediately update Crawl4AI to version 0.8.7 or later and restrict API endpoint access to trusted users only.
Original NVD description (English source)
Crawl4AI before 0.8.7 contains an arbitrary file write vulnerability in the Docker API server's /screenshot and /pdf endpoints. The output_path parameter accepts arbitrary filesystem paths without validation, allowing an attacker to supply absolute or path-traversal values to write to any location writable by the application's user, overwriting server files and causing denial of service.
