CVE-2026-59209: CWE-522: Insufficiently Protected Credentials in n8n-io n8n
n8n versions prior to 1.123.61, 2.27.4, and 2.28.1 contain a vulnerability where an authenticated user with editor access to a shared workflow can access credential-populated headers via the $request object in an HTTP Request node's pagination expression. This exposure allows the user to read and exfiltrate sensitive credentials. The issue is addressed in versions 1.123.61, 2.27.4, and 2.28.1.
AI Analysis
Technical Summary
CVE-2026-59209 is a vulnerability in the n8n workflow automation platform affecting versions before 1.123.61, 2.27.4, and 2.28.1. It allows an authenticated user with use-only editor access to a shared workflow to read sensitive credential information exposed in HTTP Request node pagination expressions via the $request object. This leads to insufficient protection of credentials (CWE-522) and unauthorized information disclosure (CWE-200). The vulnerability has a CVSS 4.0 score of 7.1 (high severity) and is fixed in the specified versions.
Potential Impact
An authenticated user with limited editor privileges can access and exfiltrate sensitive credential data embedded in HTTP Request node pagination expressions. This compromises confidentiality of credentials within the affected n8n workflows, potentially leading to unauthorized access to external systems or services that rely on those credentials.
Mitigation Recommendations
Upgrade n8n to version 1.123.61, 2.27.4, or 2.28.1 or later, where this vulnerability is fixed. Patch status is confirmed by the version information in the advisory. No additional mitigation steps are indicated.
