CVE-2018-3764

Name of the Vulnerable Software and Affected Versions Nextcloud Contacts versions prior to 2.1.2

Description The issue is related to a missing sanitization of search results for an autocomplete field, which could lead to a stored XSS requiring user-interaction. This missing sanitization only affected group names, meaning malicious search results could only be crafted by privileged users like admins or group admins.

Recommendations For versions prior to 2.1.2, update to version 2.1.2 or later to resolve the issue. As a temporary workaround, consider restricting the ability of privileged users to create or modify group names until the update is applied.
