GHSA-jp3q-wwp3-pwv9 Freeform Craft Plugin CP UI (builder/integrations) has Stored Cross-Site Scripting (XSS) issue

• Packagist solspace/craft-freeform: >= 5.0.0, < 5.14.7 → fixed in 5.14.7

Summary 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. Affected Product • Ecosystem: Packagist (Craft CMS plugin) • Package: solspace/craft-freeform • Version: `. 2. Open the form builder view containing the field. 3. Alert executes (stored XSS). • Integration icon SVG: 1. Set an integration "icon SVG" to `alert('xss-icon')`. 2. Open the integrations CP view. 3. Script executes. Impact Arbitrary JS in admin CP; session/CSRF token theft; potential full admin takeover via DOM-driven actions. Remediation • Sanitize/HTML-encode all user-controlled strings before passing to `dangerouslySetInnerHTML`, or avoid it for labels/titles/icons. • Server-side: strip/escape disallowed tags on save for fields, integration metadata, WYSIWYG content. • Add regression tests with `` payloads to ensure no execution in builder/integration views. Workarounds • Restrict form-edit permissions to trusted admins only until patched. • Consider CSP that disallows inline scripts (defense-in-depth only).
