CVE-2026-65593: Server-Side Request Forgery (SSRF) in n8n-io n8n
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.
AI Analysis
Technical Summary
CVE-2026-65593 is a server-side request forgery vulnerability affecting n8n versions prior to 1.123.64. The vulnerability arises because the dynamic-node-parameters endpoints do not enforce authorization scopes, allowing authenticated users to provide absolute URLs in routing configurations. This can override baseURL restrictions and lead the n8n server to issue HTTP requests to arbitrary internal systems if SSRF protection is disabled. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and limited confidentiality and integrity impact with high scope change.
Potential Impact
An authenticated attacker can exploit this vulnerability to make the n8n server send HTTP requests to arbitrary internal targets. This could potentially expose internal services or data that are not otherwise accessible externally. The impact is limited by the requirement for authentication and the condition that SSRF protection is disabled.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, ensure SSRF protection is enabled and restrict access to dynamic-node-parameters endpoints by enforcing proper authorization scopes. Monitor for updates from the vendor regarding patches or official mitigations.
