Any website a developer visits while the dev server is running can trigger these endpoints cross-origin with no interaction beyond the visit. An attacker can open an arbitrary existing local file in the developer&#8217;s editor, including files outside the project root, and repeated requests can spawn editor processes and force recompilations that degrade the developer&#8217;s machine.
