CVE-2026-44790 is a critical-severity vulnerability rated 9.4/10 on the CVSS scale. n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could inject CLI flags on the Git node's Push operation allowing an attacker to read arbitrary files from the n8n server potentially leading to full compromise. EPSS estimates a 0.63% chance of exploitation in the next 30 days.
