Summary
n8n: Edit Image Node Format Injection Allows Arbitrary File Write
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Restrict n8n instance access to fully trusted users only.
- Disable the Edit Image node by adding
n8n-nodes-base.editImageto theNODES_EXCLUDEenvironment variable.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
Impact
The n8n Edit Image node passed its output format to the underlying image library without validation, so a crafted value could write bytes to a location outside the node's working directory. An authenticated user able to run workflows could use this to write arbitrary files in the n8n instance.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

The issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
Frequently Asked Questions
- What is GHSA-XMC9-4F2H-JF9C? GHSA-XMC9-4F2H-JF9C is a high-severity security vulnerability in n8n (npm), affecting versions < 1.123.67. It is fixed in 1.123.67, 2.32.1, 2.31.5.
- Which versions of n8n are affected by GHSA-XMC9-4F2H-JF9C? n8n (npm) versions < 1.123.67 is affected.
- Is there a fix for GHSA-XMC9-4F2H-JF9C? Yes. GHSA-XMC9-4F2H-JF9C is fixed in 1.123.67, 2.32.1, 2.31.5. Upgrade to this version or later.
- Is GHSA-XMC9-4F2H-JF9C exploitable, and should I be worried? Whether GHSA-XMC9-4F2H-JF9C is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-XMC9-4F2H-JF9C is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
