    CVE-2026-71904

    Multiple DrayTek VigorAP models contain a command injection vulnerability in the tr069TestInform function.

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.
