About this plugin

Safe SVG is the best way to Allow SVG Uploads in WordPress!

It gives you the ability to allow SVG uploads whilst making sure that they’re sanitized to stop SVG/XML vulnerabilities affecting your site. It also gives you the ability to preview your uploaded SVGs in the media library in all views.

Current Features

  • Sanitised SVGs – Don’t open up security holes in your WordPress site by allowing uploads of unsanitised files.
  • SVGO Optimisation – Runs your SVGs through the SVGO tool on upload to save you space. This feature is disabled by default but can be enabled by adding the following code: add_filter( 'safe_svg_optimizer_enabled', '__return_true' );
  • View SVGs in the Media Library – Gone are the days of guessing which SVG is the correct one, we’ll enable SVG previews in the WordPress media library.
  • Choose Who Can Upload – Restrict SVG uploads to certain users on your WordPress site or allow anyone to upload.

Initially a proof of concept for #24251.

SVG Sanitization is done through the following library: https://github.com/darylldoyle/svg-sanitizer.

SVG Optimization is done through the following library: https://github.com/svg/svgo.

Questions

Can we change the allowed attributes and tags?

Yes, this can be done using the svg_allowed_attributes and svg_allowed_tags filters.
They take one argument that must be returned. See below for examples:

add_filter( 'svg_allowed_attributes', function ( $attributes ) {

    // Do what you want here...

    // This should return an array so add your attributes to
    // to the $attributes array before returning it. E.G.

    $attributes[] = 'target'; // This would allow the target="" attribute.

    return $attributes;
} );


add_filter( 'svg_allowed_tags', function ( $tags ) {

    // Do what you want here...

    // This should return an array so add your tags to
    // to the $tags array before returning it. E.G.

    $tags[] = 'use'; // This would allow the <use> element.

    return $tags;
} );
