solutions:
​Weintek has updated their account API to v0.13.8, which has fixed the issue. This fix does not require any action for users.
workarounds:
​Additional mitigations are recommended to help reduce risk:
*  ​Log in on trusted computers if possible. Log out after usage on un-trusted ones.
*  ​On the HMIs, if the online services are not used, set to offline mode for EasyAccess 2.0 or Dashboard services using system reserved addresses.
*  ​Regularly change passwords to reduce risks.
*  ​Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible- only applicable devices and/or systems have access to the internet.
