There are two vectors for XSS attacks with versions of @joeattardi/emoji-button before 4.6.2:
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.
This vulnerability is fixed starting in version 4.6.2. This is resolved by properly escaping strings that are inserted into the HTML document.
There is no workaround other than upgrading to a non-vulnerable version.
This issue was discovered by GitHub team member @erik-krogh (Erik Krogh Kristensen) and was reported by the GitHub Security Lab team.
