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 authentication when the embed login feature is enabled and at least one trusted key source is configured. An attacker can gain unauthorized access to any existing user account by presenting a validly-signed token with an unverified email claim from a trusted issuer.
Note: This is only exploitable if the embed login feature is enabled and at least one trusted key source is configured.
Workaround
This vulnerability can be mitigated by disabling the embed login feature by setting N8N_TOKEN_EXCHANGE_ENABLED=false, restricting network access to trusted parties only, and auditing all configured trusted keys and their allowedRoles assignments.
