Overview
n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Incorrect Authorization when saving credentials. An authenticated user can access plaintext values of secrets stored in external vaults by referencing a secret's external name in a credential, bypassing intended permission checks.
Note: This is only exploitable if an external secrets vault is configured and the attacker knows or can guess the name of a target secret.
