Privilege escalation via unchecked user-management authorization
Published Aug 10, 2026 · Updated Aug 10, 2026
Incorrect authorization in TP-Link Aginet device user management allows remote authenticated users to perform administrative actions. The user-management interface accepts low-privilege requests without enforcing authorization for higher-privilege operations. Adjacent-network access and valid low-privilege credentials are required; exploitation can create privileged accounts or alter critical configuration.
