What is CVE-2026-71913?

Multiple models of DrayTek's VigorAP series are susceptible to a command injection vulnerability within the upload_settings.cgi interface. This issue stems from inadequate filtering of input prior to the concatenation of the restorekey field into a shell command. A remote attacker, possessing valid administrative credentials for the device's web management interface, can exploit this weakness by providing manipulated input, which can result in the execution of arbitrary commands with root privileges on the affected device.
