CVE-2025-55526Public exploitNetwork attack vector

Unauthenticated file disclosure via Windows path traversal

Published Aug 26, 2025 · Updated Aug 27, 2025

Path traversal in Zie619 n8n-workflows at commit ee25413 allows remote attackers to read arbitrary server files through its download API. The download_workflow function passes the URL-derived filename to os.path.join without rejecting Windows backslash traversal, allowing the resulting path to escape the workflows directory. The unauthenticated download endpoint is remotely reachable, but the demonstrated consequence is file disclosure on Windows rather than file modification or service interruption.
