## What is CVE-2026-9151?

CVE-2026-9151 is a high-severity command injection vulnerability in TP Link Systems Inc. Archer AX12 V1, published on 10 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An OS
command injection vulnerability exists in the VPN module of TP-Link Archer AX12
v1, AX17 v1. AX18 v1, and AX1300 v1.6 routers. This vulnerability allows an
