GHSA-777W-RPR6-C52H
Vulnerability from github – Published: 2026-07-22 22:00 – Updated: 2026-07-22 22:00Impact
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.

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-48
Strategy: Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Mitigation MIT-49
Strategy: Separation of Privilege
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
CAPEC-122: Privilege Abuse
An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
CAPEC-233: Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
CAPEC-58: Restful Privilege Elevation
An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
