CVE-2026-65593PublishedWithdrawn

n8n before 1.123.64, 2.29.8, and 2.30.1 SSRF via Dynamic Node Parameters

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 versions before 1.123.64, 2.29.8, and 2.30.1 contain a server-side request forgery vulnerability in the dynamic-node-parameters endpoints that lack authorization scopes. Authenticated attackers can supply absolute URLs in routing configuration to override baseURL restrictions and make the n8n server issue HTTP requests to arbitrary internal targets when SSRF protection is disabled.

## 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, defeating the restriction meant to confine requests to the node's own upstream service. With SSRF protection disabled by default (`N8N_SSRF_PROTECTION_ENABLED=false`), this let an authenticated user make the n8n server issue HTTP requests to arbitrary internal targets. ## Patches The issue has been fixed in n8n versions 1.123.64, 2.29.8, and 2.30.1. 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: - Restrict n8n instance access to fully trusted users only. - Set `N8N_SSRF_PROTECTION_ENABLED=true` to enable SSRF filtering for private IP ranges and cloud metadata endpoints. - Restrict network egress from the n8n host to limit reachable internal services. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
