CyberRota Analysis
AI-GeneratedCrawl4AI versions prior to 0.9.0 are vulnerable to arbitrary file write due to improper handling of filenames derived from attacker-controlled input, allowing for directory traversal. This flaw can lead to remote code execution, posing a critical risk to systems utilizing the affected versions. Organizations using Crawl4AI should prioritize upgrading to version 0.9.0 or later to mitigate this severe vulnerability.

Original NVD Description
Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, when the crawler saves a downloaded file, the destination filename was taken from attacker-influenced input and joined to the downloads directory with no confinement. A filename containing an absolute path or traversal escaped the downloads directory, giving an arbitrary file write with attacker-controlled contents; the HTTP crawler path uses the response Content-Disposition filename and the browser crawler path uses the download's suggested filename. Because the written bytes are attacker-controlled, this can escalate to remote code execution. This issue is fixed in version 0.9.0.
