Medium (4.8) in nextcloud contacts. EPSS 0.6% chance of exploitation in the next 30 days.

In Nextcloud Contacts before 2.1.2, a missing sanitization of search results for an autocomplete field could lead to a stored XSS requiring user-interaction. The missing sanitization only affected group names, hence malicious search results could only be crafted by privileged users like admins or group admins.
