CVE-2026-102630: Unopim

Medium severity, CVSS 4.7. EPSS: 0.1% chance of exploitation in the next 30 days.

UnoPim versions before 2.0.1 and 2.1.1 trust all connecting clients as proxies and honor the X-Forwarded-Host header without validation, allowing unauthenticated attackers to inject arbitrary origins into admin layout pages. Attackers can set X-Forwarded-Host to redirect JavaScript asset loading to their server, and when responses are cached by shared proxies, subsequent administrators execute attacker-supplied code in their authenticated sessions.

Affected products

• Unopim Unopim: from 2.0.0, before 2.0.1 (fixed in 2.0.1); from 2.1.0, before 2.1.1 (fixed in 2.1.1)
