## What is CVE-2026-105674?

CVE-2026-105674 is a high-severity vulnerability in TP-Link Systems Inc. Tapo C325WB v2, published on 8 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

TP-Link Tapo
C325WB V2 generates the pre-shared key used by its local media streaming
service with a time-seeded pseudo-random number generator, making the key
predictable and recoverable. An unauthenticated attacker on the adjacent
network can recover the key and authenticate to the media streaming service
without valid user credentials. 

Successful
exploitation may allow an unauthenticated adjacent-network attacker to access
and take over live video and audio streams, compromising the confidentiality
and integrity of camera media.

Weakness: CWE-330 (Use of Insufficiently Random Values)
