CVE-2026-54304 · n8n: SecurityScorecard Node Leaks API Token to User-Controlled Host

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
