CyberRota Analysis
AI-GeneratedThe vulnerability affects n8n versions prior to 2.30.1 and 2.29.8, where the Token Exchange module improperly assigns all Public API key scopes to JWTs, allowing low-privileged users to perform administrator-level operations. This can lead to critical impacts such as role escalation, user management, and potentially remote code execution if Community Package installation is enabled. Organizations using n8n with the Token Exchange feature and Public API enabled should prioritize patching to mitigate these risks.

Original NVD 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.
