CVE-2026-65593: Server-Side Request Forgery (SSRF) in n8n-io n8n
n8n versions before 1.123.64 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 before 1.123.64. The issue exists in the dynamic-node-parameters endpoints, which lack proper authorization scopes. Authenticated attackers can exploit this by providing absolute URLs in routing configurations, overriding baseURL restrictions and triggering the n8n server to send HTTP requests to arbitrary internal systems when SSRF protections are not enabled.
Potential Impact
An authenticated attacker can cause the n8n server to perform HTTP requests to arbitrary internal targets, potentially exposing internal services or data. The vulnerability requires authentication and SSRF protection to be disabled for exploitation. The CVSS score of 6.3 indicates a medium impact level.
Mitigation Recommendations
No official patch or remediation level is currently confirmed. Users should upgrade to version 1.123.64 or later once available. Until then, ensure SSRF protections are enabled and restrict access to dynamic-node-parameters endpoints to trusted users only. Monitor vendor advisories for updates on fixes.
