Summary

Dashy is a self-hostable personal dashboard. From 1.9.4 until 3.2.0, the Dashy RSS Widget in src/components/Widgets/RssFeed.vue does not sanitize RSS item link values before rendering feed item titles and Read More links as anchor href attributes, allowing an attacker-controlled feed to provide a javascript: URI that executes when clicked in the Dashy origin. This issue is fixed in version 3.2.0.
