CVE-2026-54304: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in n8n-io n8n
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.
AI Analysis
Technical Summary
CVE-2026-54304 is an information exposure vulnerability in n8n's SecurityScorecard node. Authenticated users with permission to create or modify workflows and access to a SecurityScorecard credential with domain restrictions could manipulate the report download operation to send the API token to an attacker-controlled URL. This results in unauthorized disclosure of the credential, bypassing configured domain limitations. The vulnerability affects versions prior to 1.123.55, 2.25.7, and 2.26.1 and has a CVSS 4.0 score of 7.1 (high severity).
Potential Impact
An attacker with limited authenticated access can exfiltrate sensitive API tokens by abusing the SecurityScorecard node, potentially compromising the confidentiality of credentials intended to be restricted to certain domains. This could lead to unauthorized access to external services using the stolen token.
Mitigation Recommendations
This vulnerability is fixed in n8n versions 1.123.55, 2.25.7, and 2.26.1. Users should upgrade to at least these versions to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.
