CVE-2026-54304

Name of the Vulnerable Software and Affected Versions n8n versions prior to 1.123.55 n8n versions prior to 2.25.7 n8n versions prior to 2.26.1

Description An authenticated user with permissions to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains can configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attaches the SecurityScorecard API token to the outbound request, which allows the credential to be sent to an external host, bypassing configured limitations and resulting in credential exfiltration.

Recommendations Update to version 1.123.55. Update to version 2.25.7. Update to version 2.26.1. 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.
