Security Advisory: Multiple Vulnerabilities in Tapo C210 (CVE-2026-105814 & CVE-2026-105815)

Description of Vulnerabilities and Impact

CVE-2026-105814: Order-Dependent Authentication Bypass in the DS JSON API

TP-Link Tapo C210 V3.60 contains an authentication bypass vulnerability in the DS JSON API. A crafted JSON request containing both a protected operation and public onboarding-related fields may cause module-level authorization checks to be applied inconsistently, allowing protected camera operations, including pan-tilt-zoom control, to be executed without a valid authenticated session.

Successful exploitation may allow an unauthenticated attacker on the adjacent network to perform protected camera operations, including pan-tilt-zoom (PTZ) control, without a valid authenticated session. This could result in unauthorized manipulation of camera functionality.

CVSS v4.0 Score: 5.3 / Medium

CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N

CVE-2026-105815: Credential Material Exposure Leading to Unauthorized Streamed Media-Session Access

TP-Link Tapo C210 V3.60 may expose shared credential material and cryptographic metadata through unauthenticated DS JSON API requests. The exposed shared credential can be accepted by the Streamd Digest authentication mechanism as an administrative password, allowing an unauthenticated adjacent-network attacker to establish encrypted media sessions without knowledge of the device account password.

Successful exploitation may disclose credential and cryptographic material and allow unauthorized access to encrypted media sessions.

CVSS v4.0 Score: 7.1 / High
