Overview
About vulnerability
An internal regex in the Svelte runtime can take exponential time to test in<svelte:element this={tag}></svelte:element>. You are only vulnerable to this if you allow tags of unconstrained length. If your application only allows a predetermined list of tags or trims their length before passing them to svelte:element, you are safe.
