CVE-2026-102368 · Severity: info · Published 2026-10-08

The Tapo S505 is a smart Wi-Fi light switch that stores device-specific cryptographic keys in plaintext within its firmware. An attacker with physical access to the device can extract these keys and potentially compromise communications or gain unauthorized access to connected systems. This vulnerability requires physical access to the hardware, limiting its immediate risk but creating a significant exposure for stolen or compromised devices.

Vendors: [TP-Link](https://junglewise.ai/threats/vendors/tp-link).

Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in 1.4.1 Build 260713

## Technical details

The vulnerability is a cleartext storage of sensitive data flaw in the Tapo S505 firmware, where device-specific cryptographic material is stored unencrypted in nonvolatile storage. An attacker requires physical access to the device to extract and recover this material. Successful exploitation discloses the cryptographic keys, which could enable unauthorized access to protected communications or information depending on how the keys are used in the device ecosystem.

## Affected products

- TP-Link Tapo S505 v1.6
