Technical details
An arbitrary file write vulnerability exists in Crawl4AI's Docker API server within the /screenshot and /pdf endpoints. The root cause is a lack of validation for the 'output_path' parameter, which allows attackers to provide absolute paths or path traversal sequences (e.g., '../'). An unauthenticated remote attacker can exploit this to write or overwrite files anywhere the application user has write access. This can result in a Denial of Service (DoS) by overwriting critical configuration or system files. The issue is fixed in version 0.8.7 by implementing path validation that restricts writes to a specific output directory and rejects traversal sequences.
