CVE-2026-59232 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in Roskus Prospero Flow CRM versions prior to 5.3.7. The issue allows authenticated users with permission to create or update leads to execute arbitrary JavaScript in the application origin. This is achieved by injecting HTML into the lead name field, which is then rendered without proper escaping in the lead index view. The vulnerability was introduced in version 1.0.0 and exists in several subsequent releases until it was patched in version 5.3.7.
Users are advised to upgrade to Roskus Prospero Flow CRM version 5.3.7 or later.
