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

June 16, 2026 (updated July 20, 2026)

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.
