CVE-2026-105822

Server-Side Request Forgery in Tapo Cloud MQTT Proxy

Assigner: TPLink
Reserved: 05.10.2026 Published: 03.11.2026 Updated: 03.11.2026

The Tapo Cloud MQTT proxy contains a server-side request forgery (SSRF) vulnerability because it accepts a user-controlled host value without sufficient input validation. An attacker may exploit this vulnerability to cause the Tapo Cloud service to send requests to an attacker-controlled server.

Successful exploitation may cause the Tapo Cloud service to send a request to an attacker-controlled server, exposing the internal information and causing potential Distributed Denial-of-Service (DDoS).
