Description

A command

injection vulnerability has been identified in the DHCP option processing logic

in multiple TP-Link router models, due to insufficient validation of externally

supplied DHCP option data. An adjacent attacker may exploit this

vulnerability by supplying crafted DHCP responses, potentially resulting in unauthorized

command execution during device initialization or provisioning workflows. This

typically occurs when the device is in a factory-default or unconfigured state.

Successful

exploitation may allow an adjacent, unauthenticated attacker to execute

arbitrary commands with elevated privileges, potentially leading to full

compromise of the affected device and unauthorized administrative control.

Weakness class

CVE-2026-11834 is classified as CWE-78: OS Command Injection. Untrusted input reaches a shell command without neutralisation, so an attacker can run arbitrary operating system commands.

Affected software

CVE-2026-11834 is recorded against 1 package.
