# CVE-2026-102369: Unauthenticated Remote Code Execution via MacTool Command Injection in TP-Link Tapo C120 & C200

- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: V5_1.4.6 Build 260709 Rel.27675n, V1_1.9.4 Build 260813 Rel.79754n
- Published: 2026-10-01 · Updated: 2026-10-01

## Affected

- TP-Link Systems Inc. Tapo C200 v5: fixed in V5\_1.4.6 Build 260709 Rel.27675n
- TP-Link Systems Inc. Tapo C120 v1: fixed in V1\_1.9.4 Build 260813 Rel.79754n

## Description

Tapo C120 v1 and C200 V5 do not adequately protect login challenge data or sanitize attacker-controlled input processed by the MacTool handler. An unauthenticated attacker on the same local network can replay login challenge data to obtain an administrative session, enable a privileged service that becomes accessible after a reboot, and submit crafted input to execute arbitrary commands within the device management process. Successful exploitation may allow arbitrary command execution on the camera and compromise the confidentiality, integrity, and availability of the affected device. Exploitation requires access from the same local network, replay of the login challenge data, activation of the privileged service, and a device reboot.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. Tapo C200 v5, TP-Link Systems Inc. Tapo C120 v1, upgrade to a fixed version (V5_1.4.6 Build 260709 Rel.27675n, V1_1.9.4 Build 260813 Rel.79754n) per the references below.
