GHSA-7CW2-WJJ4-46P6

Vulnerability from github – Published: 2025-12-20 03:31 – Updated: 2025-12-20 03:31

Details

The HTTPS server on Tapo C200 V3 does not properly validate the Content-Length header, which can lead to an integer overflow. An unauthenticated attacker on the same local network segment can send crafted HTTPS requests to trigger excessive memory allocation, causing the device to crash and resulting in denial-of-service (DoS).

Severity ?

7.1 (High)
