CVE-2025-55523Public exploitNetwork attack vector

Arbitrary file read via unchecked download path

Published Aug 21, 2025 · Updated Aug 21, 2025

Path traversal in Agent Zero 0.8.0 through 0.9.4 allows remote attackers to read arbitrary server files through a crafted path parameter. The download_work_dir_file handler passes the request path to file_info.get_file_info and serves the resolved file without restricting it to the work directory. The public report describes unauthenticated HTTP access, while CISA assumes adjacent access with low privileges; the demonstrated consequence is file disclosure only.
