n8n before version 2.28.1 contains an information disclosure vulnerability where external secrets can be accessed via workflow node expressions outside the intended credentials scope. Authenticated project editors can read plaintext external secret values by referencing them in node expressions without needing explicit secrets access permissions. This advisory is a duplicate and has been withdrawn in favor of GHSA-2434-3x6q-8r99.
AI Analysis
Technical Summary
The vulnerability in n8n prior to 2.28.1 allows authenticated users with project editor privileges to disclose external secret values by referencing them in workflow node expressions outside the credentials scope. This occurs because external secrets are incorrectly resolved in these expressions, bypassing intended access controls. The issue is classified under CWE-639 (Authorization Bypass Through User-Controlled Key). The advisory is a duplicate and has been withdrawn, pointing to GHSA-2434-3x6q-8r99 for the original report.
Potential Impact
Authenticated project editors can read plaintext external secrets without having explicit permissions to access those secrets. This leads to unauthorized information disclosure within the affected n8n instances, potentially exposing sensitive configuration or credential data.
Mitigation Recommendations
A fix is available in n8n version 2.28.1. Users should upgrade to version 2.28.1 or later to remediate this vulnerability. Since this advisory is a duplicate and withdrawn, refer to the original advisory GHSA-2434-3x6q-8r99 for detailed remediation instructions.
