State: Published
Severity: 8.8 High
Published: Jul 12, 2026
Updated: Jul 14, 2026
Reserved: Jun 19, 2026

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.
