CVE-2026-45707low · fixedCVSS 3.1
n8n-MCP: Multi-tenant MCP requests fall back to process-level n8n credentials when tenant headers are absent or incomplete
## Summary When `ENABLE_MULTI_TENANT=true`, the HTTP transport documents that the target n8n instance is selected per-request from `x-n8n-url` / `x-n8n-key` headers. Requests that omitted those headers — or supplied only one of them — silently fell back to the process-level `N8N_API_URL` / `N8N_API_KEY` credentials configured for the operator's own n8n instance. As a result, an authenticated MCP tenant could cause n8n management calls to execute against the operator's instance instead of its ow
CVE-2026-45582low · fixedCVSS 3.1
n8n-MCP: Workflow telemetry sanitizer could retain partial values from URL-shaped node parameters
## Summary In affected versions of n8n-mcp, the workflow telemetry sanitizer could retain partial fragments of URL-shaped node parameters before sending workflow data to the project's anonymous telemetry backend. Values placed in HTTP-Request-style node parameters — such as customer or tenant identifiers, short secrets embedded in query strings, and signed request parameters — could therefore appear in stored telemetry, contrary to the collection boundary documented in `PRIVACY.md`. ## Impact

n8n-mcp affected by path traversal, redirect-following SSRF, and telemetry payload exposure
## Impact `n8n-mcp` versions before 2.50.1 contained three independently-reported issues affecting deployments that run the n8n API integration: 1. **Caller-supplied identifiers were not validated before being used as URL path segments** by the n8n API client. An authenticated MCP caller passing a crafted workflow id could cause outbound requests carrying the configured n8n API key to land on other same-origin endpoints, bypassing handler-level access controls (including `DISABLED_TOOLS`). 2.
CVE-2026-44694medium · fixedCVSS 4
n8n-mcp webhook and API client paths has an authenticated SSRF
### Summary Authenticated Server-Side Request Forgery affecting the webhook trigger tools, the n8n API client (`N8N_API_URL`), and per-request URLs supplied via the `x-n8n-url` header in multi-tenant HTTP mode. ### Impact A caller with access to the MCP session can drive HTTP requests from the n8n-mcp host to internal services and cloud metadata endpoints that the SSRF gate is meant to block. The response body is returned to the caller, making internal-service enumeration and credential theft
CVE-2026-42449low · fixedCVSS 3.1
n8n-mcp's IPv4-mapped IPv6 addresses bypass SSRF protection in validateUrlSync(), enabling full SSRF for SDK embedders
### Impact In the SDK embedder path (`N8NDocumentationMCPServer` constructor, `getN8nApiClient()`, and `validateInstanceContext()`), the synchronous URL validator in `SSRFProtection.validateUrlSync()` had no IPv6 checks. IPv4-mapped IPv6 addresses such as `http://[::ffff:169.254.169.254]` bypassed the cloud-metadata, localhost, and private-IP range checks. An attacker able to supply an `n8nApiUrl` value could cause the server to issue HTTP requests to cloud metadata endpoints (AWS IMDS, GCP, Az
