CVE-2026-11834 (GCVE-0-2026-11834)
Vulnerability from nvd – Published: 2026-06-22 17:53 – Updated: 2026-06-26 21:14
VLAI
Title
Unauthenticated Command Injection via DHCP Option Handling in Multiple TP-Link Routers
Summary
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.

Title
LAN Code Execution on TP-Link Archer MR200, Archer C20, TL-WR850N and TL-WR845N
Summary
The response coming from TP-Link Archer MR200 v5.2, C20 v5 and v6, TL-WR850N v3, and TL-WR845N v4 for any request is getting executed by the JavaScript function like eval directly without any check. Attackers can exploit this vulnerability via a Man-in-the-Middle (MitM) attack to execute JavaScript code on the router's admin web portal without the user's permission or knowledge.

Title
Logic Vulnerability on TP-Link Archer C20, Archer AX53 and TL-WR841N v13
Summary
Logic vulnerability in TP-Link Archer C20 v5, 6.0, Archer AX53 v1.0 and TL-WR841N v13 (TDDP module) allows unauthenticated adjacent attackers to execute administrative commands including factory reset and device reboot without credentials. Attackers on the adjacent network can remotely trigger factory resets and reboots without credentials, causing configuration loss and interruption of device availability.
This issue affects Archer C20 v6.0 < V6_251031, Archer C20 v5 <EU_V5_260317 or < US_V5_260419

Title
Unauthenticated Command Injection via DHCP Option Handling in Multiple TP-Link Routers
Summary
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.

Title
LAN Code Execution on TP-Link Archer MR200, Archer C20, TL-WR850N and TL-WR845N
Summary
The response coming from TP-Link Archer MR200 v5.2, C20 v5 and v6, TL-WR850N v3, and TL-WR845N v4 for any request is getting executed by the JavaScript function like eval directly without any check. Attackers can exploit this vulnerability via a Man-in-the-Middle (MitM) attack to execute JavaScript code on the router's admin web portal without the user's permission or knowledge.

Title
Logic Vulnerability on TP-Link Archer C20, Archer AX53 and TL-WR841N v13
Summary
Logic vulnerability in TP-Link Archer C20 v5, 6.0, Archer AX53 v1.0 and TL-WR841N v13 (TDDP module) allows unauthenticated adjacent attackers to execute administrative commands including factory reset and device reboot without credentials. Attackers on the adjacent network can remotely trigger factory resets and reboots without credentials, causing configuration loss and interruption of device availability.
This issue affects Archer C20 v6.0 < V6_251031, Archer C20 v5 <EU_V5_260317 or < US_V5_260419
Archer AX53 v1.0 <
