CVE-2026-102630 · Severity: medium · CVSS 4.7 · Published 2026-09-29

UnoPim is an open-source Product Information Management (PIM) platform that manages product data and digital assets. The application trusts all client connections as proxies and honors the X-Forwarded-Host header without validation, allowing attackers to inject malicious origins. By redirecting JavaScript asset loading to attacker-controlled servers and leveraging proxy caching, attackers can execute arbitrary code in the authenticated sessions of administrators.

## Technical details

The vulnerability stems from unconditional proxy trust (trustProxies at '*') in the application middleware combined with improper validation of the X-Forwarded-Host header in admin layout pages. An unauthenticated attacker can inject an arbitrary host value via the X-Forwarded-Host header, causing the server to load JavaScript assets from an attacker-controlled origin. When responses are cached by shared proxies, subsequent administrators are served the malicious cached content and execute attacker-supplied JavaScript in their authenticated browser contexts.
