New CVE NOT AVAILABLE CWE-863 (opens in a new tab)How to fix?
Upgrade n8n to version 2.31.5, 2.32.1 or higher.
Overview
n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Incorrect Authorization in the process that handles credential domain restrictions when user-supplied base or endpoint URLs are set. An attacker can exfiltrate credential secrets by configuring affected nodes to send secrets to an attacker-controlled host.
Note: This is only exploitable if a credential has domain restrictions configured and is shared with non-owner users.
Workaround
This vulnerability can be mitigated by restricting workflow creation and editing permissions to fully trusted users only, restricting credential sharing to fully trusted users only, and auditing credentials with domain restrictions for unexpected sharing relationships.
