n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the workflow setting named This workflow can be called by was enforced by the Execute Workflow node but not when a workflow was attached to an Agent as a tool. A user able to build an Agent could invoke a restricted workflow and read its returned data. The affected path is packages/cli/src/modules/agents/tools/workflow-tool-factory.ts, where executeWorkflow omitted SubworkflowPolicyChecker.checkForProject. This issue is fixed in versions 2.37.7 and 2.38.2.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.4, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited data confidentiality, limited integrity, for affected systems. Impacting 1 product from n8n organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For n8n's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
