What is CVE-2026-71905?

Multiple models of the DrayTek VigorAP series are affected by a command injection vulnerability that arises from insufficient filtering of input parameters in the ExportSettings function. This weakness allows a remote attacker, armed with valid administrative credentials, to craft specific inputs that can lead to the execution of arbitrary commands with root privileges, thereby compromising the device's security and potentially gaining unauthorized control over the network.
