New CVE NOT AVAILABLE CWE-863 (opens in a new tab)How to fix?
Upgrade n8n to version 1.123.67, 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 JS task runner. An attacker can impact the confidentiality, integrity, or availability of other users' executions by poisoning the shared module cache.
Note: This is only exploitable if the instance is multi-user and the JS task runner is configured with built-in or external modules enabled.
Workaround
This vulnerability can be mitigated by restricting instance access to fully trusted users, disabling built-in and external module access in Code nodes by unsetting NODE_FUNCTION_ALLOW_BUILTIN and NODE_FUNCTION_ALLOW_EXTERNAL, or using external runner mode with a dedicated runner per user or project.
