## Affected

- TP-Link Systems Inc. Archer AX20 V2.0: fixed in V2\_260527

## Description

An unauthenticated URL redirection vulnerability has been identified in Archer AX20 V2 due to improper validation of user-supplied URL input within the web interface. An unauthenticated attacker can craft URLs containing URL-encoded path traversal sequences. When processed by the embedded web server, these inputs may cause the device to respond with HTTP 3xx redirects to attacker-controlled external domains. This issue affects Archer AX20 V2.0: through 2.1.9 Build 20230829.

## What to do
