Critical

Base vector

Name of the Vulnerable Software and Affected Versions Tattile Smart+, Vega, and Basic device families versions 1.181.5 and prior

Description The affected devices implement an authentication token (X-User-Token) with insufficient expiration. An attacker who obtains a valid token, for example through interception, log exposure, or token reuse on a shared system, can continue to authenticate to the management interface until the token is revoked. This enables unauthorized access to device functions and data.
