CVE-2026-108473: TP-Link Kasa devices improper authentication in device-management protocol

CVE-2026-108473 · Severity: info · Published 2026-10-14

TP-Link Kasa smart home devices contain an authentication flaw in their local device-management protocol that allows an attacker on the same local network to send unauthorized commands without proper credentials. An attacker could change device settings, disrupt normal operation, or in some cases access account information linked to the cloud service. This could lead to unauthorized control of smart home devices or compromise of associated user accounts.

Vendors: TP-Link.

Technical details

The vulnerability is an improper authentication issue in the local device-management protocol of Kasa devices, allowing unauthenticated adjacent-network attackers to send management instructions and modify device state or settings. Under certain conditions involving user, mobile application, and device-cloud service interaction, account-related communications may also be insufficiently protected, exposing account information. An attacker on the adjacent network can exploit this without prior authentication or authorization.
