Overview

CVE-2026-65595 is a high-severity vulnerability. It was published on July 22, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

n8n before 2.30.1 and 2.29.8 assigns all Public API key scopes to JWTs issued through the Token Exchange module regardless of the acting user's role. On instances where the Token Exchange feature and Public API are enabled, a low-privileged user who can obtain a valid external JWT trusted by a configured issuer can use the resulting access token to invoke administrator-only Public API operations such as role escalation, user creation, and user deletion (role escalation requires an Advanced Permissions license), and, when unverified Community Package installation is enabled, achieve remote code execution.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
