📦nextcloud-vue-collections

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

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.
