CVE-2026-22222 — Tp-Link Archer Be230 Firmware security vulnerability

High CVSS 8.5

An OS Command Injection vulnerability in TP-Link Archer BE230 v1.2(web modules) allows 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.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
