CVE-2026-71539 is a high-severity vulnerability rated 8.9/10 on the CVSS scale. n8n is an open source workflow automation platform. Prior to 1.123.64, 2.29.8, and 2.30.1, the Git node clone operation allows an authenticated workflow user to swap a validated directory for a symlink before cloning, planting a crafted repository in the community node directory that loads as a custom JavaScript node after restart and executes arbitrary code on the server. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
