High Injection

CVE-2026-22226 — Command Injection Vulnerability on TP-Link Archer BE230 and AX73

A command injection vulnerability may be exploited after the admin's authentication in the VPN server configuration module on TP-Link Archer BE230 v1.2 and Archer AX73 v2. 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 AX73 v2 < 1.3.1 Build 20260430.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 2.5% (30-day exploitation probability)+13
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (TP-Link Systems Inc. Archer AX73 v2, TP-Link Systems Inc. Archer Be230 Firmware, TP-Link Systems Inc. Archer BE230 v1.2).
Apply the fixed version or the patch documented under Remediation.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
