## Overview

## Impact
An authenticated user with permission to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains could configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attached the SecurityScorecard API token to the outbound request, causing the credential to be sent to the attacker-controlled host bypassing credential configured limitations and exfiltrating.

## Patches
The issue has been fixed in n8n versions 1.123.55, 2.25.7, and 2.26.1. Users should upgrade to one of these versions or later to remediate the vulnerability.

## Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Limit workflow creation and editing permissions to fully trusted users only.
- Disable the SecurityScorecard node by adding `n8n-nodes-base.securityScorecard` to the `NODES_EXCLUDE` environment variable.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

## Affected packages

- `n8n < 1.123.55`
- `n8n >= 2.26.0, < 2.26.1`
- `n8n >= 2.0.0-rc.0, < 2.25.7`

## Remediation

Upgrade to a patched release:

- `n8n 1.123.55`
- `n8n 2.26.1`
- `n8n 2.25.7`
