HB810(US2) V1.0/1.6/2.0/2.6 vulnerability

The affected TP-Link Aginet devices contain a flaw in the web management interface where authentication checks are not consistently enforced on certain endpoints. An attacker can send specially crafted requests to bypass authentication and directly invoke privileged functionality without valid credentials. This issue arises from improper enforcement of access control mechanisms on sensitive operations. Successful exploitation may allow an unauthenticated attacker to execute privileged operations and gain full control of the device.
