CVE-2026-8263Network attack vector

Authenticated command execution via mac and ssid injection

Published May 11, 2026 · Updated May 11, 2026

OS command injection in the AC6 httpd service 15.03.06.49_multi_TDE01 allows remote authenticated users to execute commands via mac or ssid. The fromSetWirelessRepeat handler for /goform/WifiExtraSet incorporates the mac and ssid arguments into an operating-system command without effective neutralization. Administrative privileges are required, and successful exploitation can read or alter router data and interrupt service.
