CVE-2025-14186Public exploitNetwork attack vector

Authenticated browser script execution via unsanitized vpn_ip

Published Dec 7, 2025 · Updated Dec 8, 2025

Cross-site scripting in Grandstream Networks GXP1625 1.0.7.4 allows remote authenticated users to inject browser script through vpn_ip. The Network Status Page endpoint /cgi-bin/api.values.post fails to neutralize the vpn_ip value before incorporating it into browser-rendered output. Low-privileged web access and interaction by a page viewer are required; successful exploitation runs attacker-supplied script in that viewer's browser context.
