Unpatched Calix GS7 XGS routers with CVE-2026-75501 let remote attackers bypass NAT, add port forwards, and expose internal devices via WAN port 5000 without login. #Calix #CVE-2026-75501 #UPnP
Unpatched Calix flaw lets hackers bypass NAT to expose internal devices
A missing authentication flaw in Calix GS7 XGS (GS5239XG) routers lets remote attackers create port-forwarding rules and expose home-network devices to the internet without logging in. Security researcher Brian Khan Quintana disclosed CVE-2026-75501 after vendor contact attempts failed, and the current workaround is to disable UPnP or ask the ISP to do so. #Calix #GS5239XG #CVE-2026-75501 #CERTCC #BrianKhanQuintana
