CVE-2025-9520Network attack vector

Owner account takeover via unchecked password reset

Published Jan 26, 2026 · Updated Jan 26, 2026

Authorization bypass in TP-Link Systems Inc. Omada Controller before 6.0 allows remote authenticated users to hijack the Owner account. The account-management backend accepts an Owner identifier in a direct password-change request, changes the password despite returning HTTP 403, and fails to enforce the interface's role restriction. Administrator access is required; successful exploitation grants full control of the controller and its connected services.
