Two High-Severity n8n Flaws Enable Remote Code Execution

Cybersecurity researchers have identified two significant vulnerabilities in the n8n workflow automation platform that pose serious risks to users. Among these flaws is the CVE-2026-1470 vulnerability, which has been assigned a CVSS score of 9.9, indicating its critical nature. This eval injection vulnerability allows an authenticated user to bypass the Expression, potentially leading to remote code execution (RCE) on affected systems. The findings were reported by the JFrog Security Research team and published on January 28, 2026.

Details of the CVE-2026-1470 Vulnerability

The CVE-2026-1470 vulnerability is particularly concerning because it allows an authenticated user to execute arbitrary code on the server. This type of vulnerability is classified as an authentication bypass, which means that attackers who gain access to the system can exploit this weakness to run unauthorized commands or scripts. The implications of such an exploit can be severe, as it could lead to data breaches, loss of sensitive information, and compromise of system integrity.

In the context of network security, the ability to execute remote code can allow attackers to manipulate the workflow of the n8n platform, potentially affecting all processes that rely on it. This could disrupt operations, lead to data loss, or even allow for further infiltration into connected systems. Therefore, it is crucial for users of the n8n platform to understand the risks associated with the CVE-2026-1470 vulnerability and take appropriate action to mitigate these threats.

Impact on Users and Data Protection

The discovery of the CVE-2026-1470 vulnerability raises significant concerns for users of the n8n platform. As organizations increasingly rely on workflow automation tools for their operations, the security of these platforms becomes paramount. An RCE vulnerability not only jeopardizes the data handled by the platform but also poses risks to any interconnected systems and data repositories.

For individuals and organizations using n8n, it is essential to prioritize data protection strategies. This includes implementing robust security measures such as multi-factor authentication, which can help prevent unauthorized access even if an attacker exploits the CVE-2026-1470 vulnerability. Furthermore, regular monitoring of security advisories from n8n and other affected vendors is critical to staying informed about potential threats and updates.

Context

In recent years, the frequency and severity of cybersecurity incidents have escalated, making it imperative for organizations to stay vigilant. The n8n platform, designed for automating workflows, has become a valuable tool for many businesses. However, as with any software, vulnerabilities can emerge, necessitating swift action from users to protect their systems and data. Understanding the implications of vulnerabilities like CVE-2026-1470 is vital for maintaining a secure operational environment.

What to do

To protect against the risks associated with the CVE-2026-1470 vulnerability, users should take the following steps:

Update all affected software to the latest versions immediately to ensure that any security patches are applied.
Enable automatic updates where possible to stay current with security enhancements.
Monitor security advisories from n8n and other relevant vendors to remain aware of new threats.
Use a VPN like NordVPN or Surfshark to protect your internet traffic from potential interception.
Consider additional security measures such as multi-factor authentication to enhance access control.
