Vulnerability Title
Crawl4AI - Arbitrary File Write via output_path Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
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.
