What is CVE-2026-25055?
CVE-2026-25055 is a high-severity path traversal vulnerability in N8n N8n, published on 4 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
n8n is an open source workflow automation platform. Prior to versions 1.123.12 and 2.4.0, when workflows process uploaded files and transfer them to remote servers via the SSH node without validating their metadata the vulnerability can lead to files being written to unintended locations on those remote systems potentially leading to remote code execution on those systems. As a prerequisites an unauthenticated attacker needs knowledge of such workflows existing and the endpoints for file uploads need to be unauthenticated. This issue has been patched in versions 1.123.12 and 2.4.0.
