No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Craft CMS versions before 5.10.8 contain a stored cross-site scripting vulnerability in the control panel where draft names are rendered without HTML encoding in element chips and cards. A low-privilege user who can create element drafts can inject malicious JavaScript that executes in the browser of any higher-privileged user viewing the affected element, allowing account creation and other authenticated actions.
