CVE-2026-34123
On Tapo C520WS v2, restricted accounts (for example, hub users) are intended to execute only a limited set of low‑sensitivity operations.
Overview
CVE-2026-34123 is a known-severity vulnerability. It was published on June 6, 2026.
Technical description
On Tapo
C520WS v2, restricted accounts (for example, hub users) are intended to execute
only a limited set of low‑sensitivity operations. Due to a logic flaw in the
device’s API authorization mechanism, an attacker can craft requests that
leverage legitimate “method mapping” behavior to bypass whitelist restrictions,
allowing restricted operations to be masked as permitted requests and executed.
Successful
exploitation may allow an attacker (with access to a restricted account) to
execute unauthorized sensitive operations.
Depending on the operation invoked, impact could include device
resets, unintended configuration changes, or disruption of normal operation,
leading to loss of availability and integrity of the device.
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.
