CVE-2026-25631 (opens in a new tab)How to fix?
Upgrade n8n-workflow to version 1.118.0 or higher.
Overview
n8n-workflow is a Workflow base code of n8n
Affected versions of this package are vulnerable to Improper Input Validation via the credential domain validation process. An attacker can access sensitive credentials by sending requests to unintended domains using wildcard domain patterns in the allowed domains setting.
Note:
This is only exploitable if credentials are configured with wildcard domain patterns (e.g., *.example.com) in the allowed domains setting.
Workaround
This vulnerability can be mitigated by replacing wildcard domain patterns with explicit domain listings in HTTP Request credentials, reviewing and restricting workflow creation/modification permissions to trusted users only, and auditing existing workflows using HTTP Request nodes with domain-restricted credentials.
