CVE-2021-43785

@joeattardi/emoji-button is a Vanilla JavaScript emoji picker component. In affected versions there are two vectors for XSS attacks: a URL for a custom emoji, and an i18n string. In both of these cases, a value can be crafted such that it can insert a `script` tag into the page and execute malicious code.
