The Cure For Imposter Syndrome

It works.

Imposter syndrome is pop psychology term for worrying that people are going to find out you're not the real thing.

There is no international classification of disease code for imposter syndrome (with the possible exception of an extremely rare Capgras syndrome?)

Most individuals who describe themselves as worrying about imposter syndrome probably have a different problem, from a “taxonomy of validated psychiatric diagnosis” standpoint.

That having been said, I would argue there's a cure. And it's simple.
