  1. Fix DOM Clobbering Gadget found in rollup bundled scripts that leads … 

    …to XSS

## Descriptions
We discovered a DOM Clobbering vulnerability in rollup when bundling scripts that use `import.meta.url` or with plugins that emit and reference asset files from code in `cjs/umd/iife` format. The DOM Clobbering gadget can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized `name` attribute) are present.

### Backgrounds
DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering.
