CVE-2026-65317

Verba (goldenverba) Server-Side Request Forgery via /api/connect and Same-Origin Middleware Bypass

Published Jul 21, 2026 CVSS 4.0 · 9.2 Critical EPSS < 1% KEV · Not listed
Description
Verba RAG application version 2.1.3 contains a server-side request forgery vulnerability combined with a same-origin middleware bypass that allows unauthenticated remote attackers to make the server issue arbitrary HTTP requests by supplying a crafted Origin header and attacker-controlled host and port values. Attackers can bypass the localhost origin check in the API middleware by sending any Origin value prefixed with ' regardless of port, then submit arbitrary host and port parameters to the /api/connect endpoint to cause the server to issue outbound GET requests to attacker-controlled infrastructure.
