9.1

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H

Name of the Vulnerable Software and Affected Versions Crawl4AI versions prior to 0.8.7

Description An arbitrary file write issue exists in the Docker API server. The '/screenshot' and '/pdf' endpoints do not validate the output path parameter, which allows an attacker to use absolute paths or path-traversal sequences to write files to any location accessible by the application user. This can lead to the overwriting of server files and result in a denial of service.

Recommendations Update to version 0.8.7 or later. As a temporary mitigation, restrict access to the '/screenshot' and '/pdf' endpoints or avoid using the output path parameter until the update is applied.

Fix

Path traversal
