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.8.7CVE-2026-11834tp link systems inc.archer mr402 v1+6

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.8.5CVE-2026-75616tp-link systems inc.archer c20 v6+1

An OS command injection vulnerability exists in the web management interface of Archer C20 v6 firmware when processing certain WAN-related configuration operations. An authenticated administrator may exploit insufficient input validation to execute arbitrary system commands, potentially resulting in full device compromise. Successful exploitation may allow arbitrary command execution with elevated privileges, compromising the confidentiality, integrity, and availability of the affected device and network traffic passing through it.5.2CVE-2026-12001tp link systems inc.tl-wr845n v4+4

A hardcoded credential vulnerability exists in the firmware of multiple TP-Link routers (TL-WR845N v4, TL-WR850N v3, TL-WR902AC v4, Archer C20 v6 & Archer MR200 v5).  Authentication-related credential material is embedded within a password file in the firmware image and may be recovered through firmware analysis. Successful exploitation could result in unauthorized access to privileged functions on affected devices.
