Versions of nextcloud-vue-collections prior to 0.4.2 are vulnerable to Cross-Site Scripting (XSS). The v-tooltip component has an insecure defaultHTML configuration that allows arbitrary JavaScript to be injected in the tooltip of a collection item. This allows attackers to execute arbitrary code in a victim's browser.

Recommendation

Upgrade to version 0.4.2 or later.
