I'm no javascript framework expert, but how vulnerable do people estimate other frameworks like Angular, Sveltekit and Nuxt to be to this sort of thing? Is React more disposed to be at risk? Is it just because there are more eyes on React due to its popularity?
nuxt, sveltekit etc don't have RSC equivalent. and won't have in future either. Vue has discussed it and explicitly rejected it. also RSC was proposed to sveltekit, they also rejected it citing public endpoint should not be hidden
they may get other vulnemerelities as they are also in JS, but RSC class vulelnebereleties won't be there
