CVE-2026-25055Network attack vector

Remote file write via unsanitized SSH filename

Published Feb 4, 2026 · Updated Feb 4, 2026

Path traversal in the SSH node in affected n8n releases allows remote attackers to write files outside the selected remote directory. The upload operation appends attacker-controlled binary metadata filenames to the configured SSH path without stripping Unix or Windows directory components or null bytes. Reachability requires a known workflow with an unauthenticated file-upload endpoint feeding an SSH upload; the resulting remote file write can enable code execution on the SSH server.
