GHSA-8342-988Q-86CR n8n: Account Takeover via Unverified Email Claim in Token Exchange Embed Login

Impact In an n8n instance, when a validly-signed incoming token was matched to a local account by its email claim, the service did not check that the trusted key's permitted role ceiling covered that account, nor that the email claim was verified. As a result, anyone able to obtain a token accept...

GHSA-35Q8-9MJ6-WJMF n8n: SSO Instance-Role Provisioning Allows Privilege Escalation to Instance Owner

Impact n8n's Enterprise SSO instance-role provisioning maps a role claim asserted by the configured Identity Provider IdP to an n8n global role and applies it during authentication. The provisioning path did not prevent assignment of the global:owner role, unlike the token-exchange identity path,...

n8n: Authenticated SSRF via Dynamic Node Parameters Endpoints Allows Internal Network Access

Impact Endpoints in /rest/dynamic-node-parameters/ lacked authorization scopes, making it reachable by any authenticated user with no workflow creation or execution required. By supplying an absolute URL in the routing configuration, a caller could override the node type's declared baseURL,...

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

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...

n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution

Impact When an n8n instance is configured with more than one trusted token-exchange issuer, external identities are resolved to local accounts using only the JWT sub claim, ignoring the issuer iss. As a result, two different issuers that emit the same subject value map to the same local account. ...

GHSA-MQ3M-F8X3-579W n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution

Impact When an n8n instance is configured with more than one trusted token-exchange issuer, external identities are resolved to local accounts using only the JWT sub claim, ignoring the issuer iss.

GHSA-H44J-F5R5-PH73 n8n: "Allowed HTTP Request Domains" Restriction Bypass via AI Agents MCP Connector

Impact The AI Agents feature did not enforce the "Allowed HTTP Request Domains" restriction configured on credentials. As a result, a member-level user who had been granted use-only access to a shared credential could cause its secret to be sent to an external server they control, by pointing an...

n8n: Shared Credential Header Leak via HTTP Request Pagination Expression

Impact An authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression. When an HTTP Header Auth credential is applied to a paginated request, the secret is present...

CRLF Injection
