Syncfusion Blazor Security

Content Security Policy (CSP) configuration for Syncfusion Blazor components in browser-hosted applications (.NET 8, 9, 10).

When to Use

Use this skill when you need to:

  • Add a CSP <meta> tag to App.razor or index.html for Syncfusion components
  • Configure CSP for self-hosted (Static Web Assets) script and style delivery
  • Configure CSP for CDN-hosted Syncfusion scripts and styles
  • Understand which CSP directives Syncfusion components require and why

Quick Reference

Required CSP Directives at a Glance

Directive Value Reason
font-src 'self' data: Base64-encoded icon fonts
style-src 'self' 'unsafe-inline' Inline styles for sizing/positioning
script-src 'self' Dynamic code evaluation (animations, etc.)
connect-src 'self' https: wss: WebSocket and HTTPS connections
img-src data: https: Inline images and remote assets
object-src 'none' Block plugin content

CDN users: also append https://cdn.syncfusion.com/blazor/ to script-src and style-src.
