CVE-2026-10562 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. 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.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
