CVE-2026-10562 (GCVE-0-2026-10562)

Vulnerability from cvelistv5 – Published: 2026-06-30 20:34 – Updated: 2026-07-01 15:38

Title

Unauthenticated Open Redirect Vulnerability on TP-Link Archer AX20 Web Interface

Summary

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.

Severity

5.9 (Medium)
