Authenticated service disruption via uninitialized offset type
Published Aug 7, 2026 · Updated Aug 7, 2026
Use of an uninitialized variable in WonderTrader 0.9.0 through 0.9.9 allows remote authenticated users to interrupt trading services. The WTSOrderInfo constructor leaves m_offsetType unset when no entrust object is supplied, while later accessors and TraderATP cash-trade conversion consume the field. Exploitation requires low-privileged network access and affects availability, with no reported confidentiality or integrity impact.
