CVE-2026-65593: n8n Authenticated SSRF Vulnerability
MODERATECVE-2026-65593 is a MODERATE authenticated ssrf vulnerability (CWE-918: Server-Side Request Forgery (SSRF)) affecting n8n libraries in the npm ecosystem. The issue involves authenticated ssrf via dynamic node parameters endpoints allows internal network access. Remediation is available by upgrading affected packages to version 1.123.64, 2.30.1, 2.29.8.
CVE-2026-65593 at a Glance
How to Fix CVE-2026-65593
To remediate this vulnerability, upgrade all affected n8n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install n8n@1.123.64npm install n8n@2.30.1npm install n8n@2.29.8Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls n8nHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-65593, inspect your project dependencies using npm:
npm ls n8nAnalyze the terminal output to locate any version of n8n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.123.64), your application is affected.
Note: The npm ls n8n command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In n8n, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "## Impact\n\nEndpoints in `/rest/dynamic-node-parameters/` lacked authorization scopes, making it reachable by any authenticated user with no workflow creation or execution required.\n\nBy 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.\n\n## Patches\nThe 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.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Set `N8N_SSRF_PROTECTION_ENABLED=true` to enable SSRF filtering for private IP ranges and cloud metadata endpoints.\n- Restrict network egress from the n8n host to limit reachable internal services.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.",
