n8n before 2.29.8 and 2.30.1 Privilege Escalation via Token Exchange

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

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.

## Impact JWTs issued through the Token Exchange module were assigned all Public API key scopes, regardless of the acting user's actual role. A low-privileged user who could obtain a valid external JWT trusted by a configured issuer could therefore use the resulting access token to invoke administrator-only Public API operations, such as role escalation, user creation, and user deletion. The issue only affects instances where the Token Exchange feature and the Public API are enabled (N8N_TOKEN_EXCHANGE_ENABLED=true, N8N_ENV_FEAT_TOKEN_EXCHANGE=true) and the attacker can obtain an external JWT accepted by a configured trusted key. Role escalation additionally requires an Advanced Permissions license; Community Package installation additionally requires `N8N_COMMUNITY_PACKAGES_ENABLED=true` and `N8N_UNVERIFIED_PACKAGES_ENABLED=true`. ## Patches The issue has been fixed in n8n version 2.30.1 and 2.29.8. Users should upgrade to this version or later to remediate the vulnerability. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Disable the Token Exchange feature by setting `N8N_TOKEN_EXCHANGE_ENABLED=false` or `N8N_ENV_FEAT_TOKEN_EXCHANGE=false`. - If Token Exchange cannot be disabled, restrict Public API access at the network level to trusted clients only. - Disable unverified Community Package installation by setting `N8N_UNVERIFIED_PACKAGES_ENABLED=false` to eliminate the code execution path. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
