int _wexecvpe(const wchar_t *cmdname, const wchar_t *const *argv, const wchar_t *const *envp)

Resolution

When you are warned about a use of one of these functions, make sure that the cmdname argument is a fully-specified path name (including file extension) from a trusted source.

Once you are satisfied that these conditions hold, you can change the warning state to Suppressed.

Relevant Configuration File Parameters
