CVE-2026-54304 (GCVE-0-2026-54304)

Vulnerability from cvelistv5 – Published: 2026-06-23 15:48 – Updated: 2026-06-23 17:18

Title

n8n: SecurityScorecard Node Leaks API Token to User-Controlled Host

Summary

n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.1, 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. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.1.

GHSA-RM2V-H48J-895M

Vulnerability from github – Published: 2026-06-16 23:34 – Updated: 2026-07-20 13:44

Summary

n8n: SecurityScorecard Node Leaks API Token to User-Controlled Host

Details

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.
