Description
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in the n8n node that fails to validate resource identifiers. Attackers can craft malicious resource IDs to redirect API calls to unintended resources, allowing unauthorized access to workflows, executions, and credential secrets within the API key's scope.
