CVE-2026-44790: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in n8n-io n8n
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. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.
AI Analysis
Technical Summary
CVE-2026-44790 is an argument injection vulnerability (CWE-88) in the n8n workflow automation platform. Specifically, authenticated users authorized to create or modify workflows can inject CLI flags into the Git node's Push operation. This flaw allows attackers to read arbitrary files on the server hosting n8n, which may lead to complete system compromise. The issue affects versions prior to 1.123.43, 2.22.1, and 2.20.7 and is resolved in these fixed releases. The vulnerability has a critical severity with a CVSS 4.0 score of 9.4.
Potential Impact
An attacker with authenticated access and workflow modification permissions can exploit this vulnerability to inject command-line arguments in the Git Push operation, enabling arbitrary file reads on the n8n server. This can potentially escalate to full system compromise, posing a severe risk to confidentiality and integrity of the affected system.
Mitigation Recommendations
A fix is available in n8n versions 1.123.43, 2.22.1, and 2.20.7. Users should upgrade to these versions or later to remediate this vulnerability. No vendor advisory content contradicts this; therefore, upgrading is the recommended mitigation.
