CVE-2026-71908· NVD / CVE Program· CNA VulnCheck

DrayTek VigorAP Multiple Models OS Command Injection via mesh_start_speed_test

Multiple DrayTek VigorAP models contain a command injection vulnerability in the mesh_start_speed_test function. The vulnerability is caused by insufficient sanitization of the meshdevice_index and meshdevice_ip fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.
