CVE-2026-7096Public exploitNetwork attack vector

Authenticated command execution via unsanitized GPON identifier

Published Apr 27, 2026 · Updated Apr 27, 2026

OS command injection in Tenda HG3 Firmware 2.0 300003070 allows remote authenticated users to execute commands via fmgpon_loid. The formgponConf handler at /boaform/admin/formgponConf incorporates the request value into an operating-system command without neutralizing command syntax. Low-privileged access to the network management interface is required, and successful exploitation compromises the device.
