SafeSVG

A free, libre and open-source tool to sanitise SVG content in .NET applications.

Build status Nuget version Licence

Features

  • Removes potentially dangerous elements and attributes from SVG files (like <script> and onload).
  • Adds (by default, if missing) the SVG xmlns attribute to the root element.
  • Removes (by default) comments from the SVG content.
  • Supports .NET 8 and 9.

Usage

  1. Install the NuGet package:

    dotnet add package Costasdev.SafeSvg
    
  2. Use the SafeSvg class to sanitise SVG content:

     using Costasdev.SafeSVG;
    
     var svgContent = "<svg><script>alert('XSS');</script></svg>";
     var safeSvg = SvgSanitiser.Sanitise(svgContent);
     Console.WriteLine(safeSvg); // <svg xmlns="http://www.w3.org/2000/svg"></svg>
    
  3. You can also provide custom options:

    using Costasdev.SafeSVG;
    
    var svgContent = "<svg><script>alert('XSS');</script></svg>";
    var options = new SvgSanitiserOptions
    {
        AddNamespace = false, // Adds the default SVG namespace (http://www.w3.org/2000/svg) if missing.
        IndentOutput = true, // Indents the output SVG using XmlTextWriter's Formatting.Indented
        RemoveComments = true // Removes comments from the SVG content.
    };
    var safeSvg = SvgSanitiser.Sanitise(svgContent, options);
    Console.WriteLine(safeSvg); // <svg xmlns="http://www.w3.org/2000/svg"></svg>
