CVE-2026-54304 Details
Description
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.
A vulnerability exists in n8n versions prior to 1.123.55, 2.25.7, and 2.26.1, allowing an authenticated user with permissions to create or modify workflows and access to a SecurityScorecard credential with restricted domains to exfiltrate the API token. By configuring the SecurityScorecard node's report download operation to target an attacker-controlled URL, the node would inadvertently send the API token to the specified host, bypassing domain restrictions and leading to unauthorized credential exposure.
Users are advised to upgrade to n8n versions 1.123.55, 2.25.7, or 2.26.1. If an immediate upgrade is not possible, consider limiting workflow permissions to trusted users and disabling the SecurityScorecard node by adding 'n8n-nodes-base.securityScorecard' to the 'NODES_EXCLUDE' environment variable.
