The commit diff shows critical changes in JavascriptProxy.cpp's proxy function call handling. The patch introduces a conditional check (isNewCall) to determine whether to include the NewTarget flag and the newTarget argument. Previously, these were always added, regardless of whether the call was a constructor. This mismatch between argument count preparation and actual usage could corrupt memory buffers, enabling RCE. The CWE-119 alignment and the explicit fix for 'unnecessary NewTarget passing' confirm this is the root cause.
