Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
Secret Exfiltration describes the vulnerability class recorded for this advisory. The current record does not mark CVE-2026-59259 as known exploited; continue to monitor the source for status changes. This is a product-level record in the current feed, not a package-level dependency mapping.
Affected software not mapped. Review the upstream record for vendor-specific product and version guidance.
n8n before versions 1.123.61, 2.27.4, and 2.28.1 contains a permission bypass vulnerability in external secrets handling caused by a mismatch between the static validation check and the runtime expression engine. An authenticated user with credential create or update permissions but without the externalSecret:list scope can embed external secret references into credentials in forms the static validation does not detect; these references resolve at workflow execution time, exposing secret values the user is not authorized to access. This issue only affects instances where an external secrets provider is configured and Advanced Permissions are in use.
