Cross-site scripting via clobbered currentScript lookup
Published Sep 17, 2024 · Updated Sep 18, 2024
DOM clobbering in Vite bundled scripts allows attackers to execute JavaScript through attacker-controlled scriptless HTML. Generated asset resolution trusts document.currentScript.src without first confirming that currentScript is a script element, so a named DOM element can supply an attacker-controlled import base. Exploitation requires a cjs, iife, or umd build with a dynamic asset import and a page that accepts an unsanitized name or id attribute.
