Tp-Link Archer Be230 Firmware

CVE-2026-0631

An OS Command Injection vulnerability in OpenVPN modules in TP-Link Archer BE230 v1.2, BE3600v1 and AXE75 v1 allows an adjacent authenticated attacker to execute arbitrary code. Successful exploitation could allow an attacker to gain full administrative control of the device, resulting in severe compromise of configuration integrity, network security, and service availability. This CVE covers one of multiple distinct OS command injection issues identified across separate code paths. Although similar in nature, each instance is tracked under a unique CVE ID. This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420 and Archer AXE75 v1 < 1.5.6 Build 20260623.
