CVE-2026-15315

Technical Description

Tapo C120 v1 and C200 v5

contain an improper authentication vulnerability within the login

authentication verification module. An attacker on the local network can

exploit weaknesses in challenge parameter validation to bypass normal

authentication controls and obtain administrative session tokens.

Successful

exploitation may allow an attacker to subsequently execute privileged

management actions, enable unauthorized administrative access and temporary

disruption of device services, resulting in a denial-of-service (DoS)

condition.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
