CVE-2026-56260 [CRITICAL] – Crawl4AI before 0.8.7 contains an arbitrary file write vulnerability in the Docker API ser

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.
