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 via the genericAuthType in the HTTP Request node. An attacker can gain unauthorized access to credentials belonging to other users by referencing another user's credential through an expression, which bypasses the intended ownership check during execution.
Note: This is only exploitable if the attacker knows the identifier of the target credential.
Workaround
This vulnerability can be mitigated by restricting instance access to fully trusted users, excluding the HTTP Request node by setting the NODES_EXCLUDE environment variable to include n8n-nodes-base.httpRequest, and auditing credential sharing and workflow access to limit exposure of credential IDs to untrusted users.
