Safe SVG

Автор: 10up

Описание

Safe SVG — лучший способ разрешить загрузку SVG в 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

  • Санитарные SVG-файлы — Не открывайте дыр в безопасности на своем сайте WordPress, разрешив загрузку файлов без проверки.
  • Просмотр SVG в библиотеке медиафайлов — Прошли те времена, когда мы угадывали, какой SVG является правильным, мы включим предварительный просмотр SVG в библиотеке мультимедиа WordPress.

Features on the Roadmap

  • Оптимизация SVGO — У вас будет возможность запустить SVG через наш сервер SVGO при загрузке, чтобы сэкономить ваше место.
  • Выберите, кто может загружать — Ограничьте загрузку SVG определенным пользователям на вашем сайте WordPress или разрешите кому-либо загружать.

Initially a proof of concept for #24251.

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

Установка

Установить прямо через WordPress, либо загрузить, распаковать и выгрузить файлы в директорию /wp-content/plugins/ вашего сайта

Часто задаваемые вопросы

Можем ли мы изменить разрешенные атрибуты и метки?

Да, это возможно, используя фильтры svg_allowed_attributes и svg_allowed_tags.
Они принимают аргумент, который должен быть возвращен. Смотрите ниже примеры:

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;
} );

Incredibly useful!

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 🙂

Agency go-to for SVG uploads

14.02.2022
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.

Updated! Feb 23rd 2022

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!

Should be default in WP

WP should incorporate this plugin asap. SVG support is now common everywhere and we still have to rely on a plugin that is no longer maintained and is clearly the best IMHO.
