Official description

Tattile Smart+, Vega, and Basic device families firmware versions 1.181.5 and prior implement an authentication token (X-User-Token) with insufficient expiration. An attacker who obtains a valid token (for example via interception, log exposure, or token reuse on a shared system) can continue to authenticate to the management interface until the token is revoked, enabling unauthorized access to device functions and data.
