Cross-site Scripting in the lead index view in Roskus Prospero Flow CRM before 5.3.7 allows authenticated users holding the create or update lead permission to execute arbitrary JavaScript in the application origin via HTML markup stored in the lead name field, which the view renders through Blade's unescaped output directive and inside a JavaScript string literal in an onclick attribute.
