- Summary
- Duplicate Advisory: n8n: Privilege Escalation and Code Execution via Full Public API Key Scope Assignment to Token Exchange JWTs

Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-777w-rpr6-c52h. This link is maintained to preserve external references.
Original 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.
