Remote Code Execution in n8n via GraphicsMagick Image Processing

Publication date: 2026-11-13

Last updated on: 2026-11-13

Assigner: VulnCheck

Description
n8n before 1.123.89, 2.x before 2.45.5, 2.46.x before 2.46.1, and 3.x before 3.0.1 bundles a GraphicsMagick version with known vulnerabilities in its official Docker image, which the Edit Image node uses to process images. Attackers who can supply crafted untrusted images to an Edit Image workflow, such as one fed by a Webhook node, can execute code on the n8n instance.

Executive Summary

CVE-2026-126384 is a vulnerability in n8n versions before 1.123.89, 2.x before 2.45.5, 2.46.x before 2.46.1, and 3.x before 3.0.1. It involves a vulnerable GraphicsMagick component bundled in the official Docker image. Attackers can exploit this by sending crafted images to an Edit Image workflow, such as via a Webhook node, to execute arbitrary code on the n8n instance.

Detection Guidance

Check n8n version with 'docker inspect <container_name> | grep n8n' or 'n8n --version'. Inspect Docker images for GraphicsMagick with 'docker exec <container_name> gm -version'. Monitor logs for Edit Image node processing untrusted images.

Impact Analysis

This vulnerability allows attackers to execute code on your n8n instance if they can supply malicious images to an Edit Image workflow. This could lead to unauthorized access, data breaches, or disruption of services. The impact includes potential loss of confidentiality, integrity, and availability of the system.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Organizations may face legal penalties, reputational damage, and loss of trust if sensitive data is exposed due to this issue.

Mitigation Strategies

Upgrade n8n to patched versions (1.123.89+, 2.45.5+, 2.46.1+, 3.0.1+). Disable the Edit Image node if unused. Restrict access to trusted users and audit workflows. Remove vulnerable GraphicsMagick coder modules.
