Safe SVG

説明

Safe SVG は、WordPress で SVG のアップロードを許可する最良の方法です !

サイトに影響を与える SVG/XML の脆弱性を阻止するためにサニタイズされていることを確認しながら、SVG のアップロードを許可することができます。 また、メディア ライブラリにアップロードした SVG をすべてプレビューすることもできます。

現在の機能

  • サニタイズされた SVG – サニタイズされていないファイルのアップロードを許可して、WordPress サイトにセキュリティ ホールを開かないでください。
  • メディア ライブラリで SVG を表示 – どの SVG が正しいかを推測する時代は終わりました。WordPress メディア ライブラリでSVG プレビューを有効にします。

ロードマップでの機能

  • SVGO の最適化 – スペースを節約するために、アップロード時に SVGO サーバーを介して SVG を軽量化します。
  • アップロードできるユーザーを選択 – SVG のアップロードを WordPress サイトの特定のユーザーに制限するか、誰でもアップロードできるようにします。

最初は #24251 の概念実証です。

SVG のサニタイズは、次のライブラリを通じて行われます: https://github.com/darylldoyle/svg-sanitizer

インストール

WordPress ディレクトリからインストールするか、ファイルをダウンロードして解凍し、 /wp-content/plugins/ ディレクトリにアップロードします

FAQ

許可された属性とタグを変更できますか ?

はい、 svg_allowed_attributes および svg_allowed_tags フィルターを使用して行うことができます。
返されなければならない 1 つの引数を取ります。 例については、以下を参照してください:

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;
} );

Why Automattic hates SVG has always been a source of confusion to me. Why shouldn't uploading SVG be as easy and straightforward as any other kind of (supported) image? Then again, it's true that you can write malicious code inside a SVG rather easily. The solution? Safe SVG. It cleans up a malformed or malicious SVG during the upload, so that when it arrives in your Media Library, it will already have been sanitised. The plugin is as simple to operate as it is useful. All parts of WP that require opening the Media Library browser will now accept SVGs as well. As others have remarked, there are some outstanding issues when previewing SVGs inside Gutenberg. No surprises there — this plugin has predated Gutenberg, and (at the time of writing) has been abandoned for about two years, during which Automattic has been eagerly upgrading WordPress. The author has not gone away, though. He is still actively developing the sanitising part of the plugin, using a library he has developed and posted on GitHub, and which has accepted several contributions and gone through many code reviews. It's possibly the reference library for SVG sanitation written in PHP. And fortunately he's now back and has released a brand new version as of late February 2022 🙂

Our agency has a talented illustrator who is adept at creating SVGs, particularly with self-contained CSS animations. We would be loading them all manually from the theme folder with no path to easily add new or replace existing SVGs without developer involvement if it weren't for this plugin. We install Safe SVG on pretty much all sites we custom build for our clients. I'm really hoping for some additional features to come to this plugin to better support the Gutenberg editor, since the core image block doesn't handle SVGs well. But that doesn't affect my 5-star review as the most reliable SVG upload plugin.

I used to install this plugin on all clients' websites, but sadly, the plugin has been not upgraded for 2 years! so i replaced it for another one. Updated review, the plugin finally has been updated, so all good now!
