CVE-2026-54443: CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) in lissy93 dashy
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.
AI Analysis
Technical Summary
The Dashy RSS Widget (src/components/Widgets/RssFeed.vue) in versions 1.9.4 through 3.1.x fails to sanitize RSS feed item link values before rendering them as anchor href attributes. This improper neutralization of script-related HTML tags (CWE-80) allows an attacker controlling the RSS feed to inject javascript: URIs that execute in the context of the Dashy origin when a user clicks the link. The vulnerability is classified as a basic XSS and is resolved in Dashy version 3.2.0.
Potential Impact
An attacker who controls an RSS feed can craft malicious javascript: URIs in feed item links that execute when a user clicks them in the vulnerable Dashy dashboard. This can lead to script execution in the Dashy origin, potentially enabling actions such as session hijacking or other client-side attacks. The CVSS 4.0 score is 5.9 (medium severity), reflecting the need for user interaction and high attack complexity.
Mitigation Recommendations
Upgrade Dashy to version 3.2.0 or later, where this vulnerability is fixed. There is no official patch or temporary fix other than upgrading. Users should avoid using untrusted RSS feeds until the upgrade is applied.
