This affects the CLI only. It does not affect the standard GUI desktop Nextcloud clients, and it does not affect the Nextcloud server.
CVE-2018-3764 1 Nextcloud 1 Contacts 2023-03-03 3.5 LOW 4.8 MEDIUM
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.
CVE-2019-5476 1 Nextcloud 1 Lookup-server 2023-03-03 7.5 HIGH 9.8 CRITICAL
