Does someone know why the Webb telescope give this strange "sharp glare" on many of the shiny star-shaped objects ? Is it some sort of AI upscaling or is it raw

Does someone know why the Webb telescope give this strange "sharp glare" on many of the shiny star-shaped objects ?
Is it some sort of AI upscaling or is it raw data coming from the sensors ?

The spikes are more noticeable on brighter point like objects like stars. https://en.wikipedia.org/wiki/Diffraction_spike https://en.wikipedia.org/wiki/Diffraction_spike
