Technical details
A Cross-Site Scripting (XSS) vulnerability exists in Dashy's workspace view due to improper input validation of the 'url' query parameter. In 'src/views/Workspace.vue', the 'getInitialUrl()' function retrieves the URL from the query string and assigns it directly to an iframe's 'src' attribute in 'src/components/Workspace/WebContent.vue' without validating the URI scheme. An attacker can provide a 'javascript:' URI which, when loaded by a logged-in victim, executes arbitrary JavaScript in the context of the Dashy origin. This allows for the theft of same-origin browser data and unauthorized interaction with the Dashy DOM. The issue is resolved in version 4.3.7 by implementing URL sanitization.
