What happened
A Max-Severity Ni8mare flaw allows full server takeover of n8n automation servers. Improper input validation in workflows allows remote command execution, potentially leading to data theft or deployment of ransomware. The flaw affects both self-hosted and Dockerized instances prior to patched versions.
Who is affected
Organizations using n8n for automation are directly exposed, potentially impacting connected applications and workflow integrity.
Why CISOs should care
Unpatched automation platforms allow lateral movement and persistence, threatening operational continuity and sensitive process data.
3 practical actions
Apply security patches: Upgrade n8n instances to versions addressing the Ni8mare flaw.
Restrict external workflow access: Limit HTTP endpoint exposure to trusted networks.
Audit automation logs: Detect abnormal workflow execution or unauthorized commands.
