Solspace Freeform plugin affected by Stored Cross-Site Scripting (XSS) in Freeform Craft Plugin CP UI (builder/integrations)_CVE-2026-26188

{
    "lastseen": "",
    "description": "Solspace Freeform plugin for Craft CMS 5.x is a super flexible form-building tool. An authenticated, low-privilege user (able to create/edit forms) can inject arbitrary HTML/JS into the Craft Control Panel (CP) builder and integrations views. User-controlled form labels and integration metadata are rendered with dangerouslySetInnerHTML without sanitization, leading to stored XSS that executes when any admin views the builder/integration screens. This vulnerability is fixed in 5.14.7.",
