Malicious npm Package Targets Solana Developers and Hijacks Funds
A malicious npm package targets Solana developers, rerouting funds in 2% of transactions to a hardcoded address.
vue-dompurify-html
Advanced tools
A "safe" replacement for the v-html
directive. The HTML code is
sanitized with DOMPurify before being interpreted.
This is only a small wrapper around DOMPurify to ease its usage in a Vue app. You should take a look at the DOMPurify Security Goals & Threat Model to understand what are the limitations and possibilities.
npm install vue-dompurify-html
The current version is only compatible with Vue 3. If you need Vue 2 support use a 4.1.x version.
You can see setup examples in the examples/ folder.
import { createApp } from 'vue';
import App from './App.vue';
import VueDOMPurifyHTML from 'vue-dompurify-html';
const app = createApp(App);
app.use(VueDOMPurifyHTML);
app.mount('#app');
In your SFC:
<template>
<div v-dompurify-html="rawHtml"></div>
</template>
<script setup>
import { ref } from 'vue';
const rawHtml = ref('<span style="color: red">This should be red.</span>');
</script>
You can also define your DOMPurify configurations:
import { createApp } from 'vue';
import App from './App.vue';
import VueDOMPurifyHTML from 'vue-dompurify-html';
const app = createApp(App);
app.use(VueDOMPurifyHTML, {
namedConfigurations: {
svg: {
USE_PROFILES: { svg: true },
},
mathml: {
USE_PROFILES: { mathMl: true },
},
},
});
app.mount('#app');
Your configuration keys can then be used as an argument of the directive:
<template>
<div v-dompurify-html="rawHtml"></div>
<div v-dompurify-html:svg="svgContent"></div>
</template>
<script setup>
import { ref } from 'vue';
const rawHtml = ref('<span style="color: red">This should be red.</span>');
const svgContent = ref('<svg><rect height="50"></rect></svg>');
</script>
Alternatively, you can define a default DOMPurify configuration:
import { createApp } from 'vue';
import App from './App.vue';
import VueDOMPurifyHTML from 'vue-dompurify-html';
const app = createApp(App);
app.use(VueDOMPurifyHTML, {
default: {
USE_PROFILES: { html: false },
},
});
app.mount('#app');
The default
DOMPurify configuration will be used:
<template>
<div v-dompurify-html="rawHtml"></div>
</template>
<script setup>
import { ref } from 'vue';
const rawHtml = ref('<span style="color: red">This should be red.</span>');
</script>
There is also the possibility to set-up DOMPurify hooks:
import { createApp } from 'vue';
import App from './App.vue';
import VueDOMPurifyHTML from 'vue-dompurify-html';
const app = createApp(App);
app.use(VueDOMPurifyHTML, {
hooks: {
uponSanitizeElement: (currentNode) => {
// Do something with the node
},
},
});
app.mount('#app');
If needed you can use the directive without installing it globally:
<template>
<div v-dompurify-html="rawHtml"></div>
</template>
<script setup lang="ts">
import { buildVueDompurifyHTMLDirective } from '../src/';
const vdompurifyHtml = buildVueDompurifyHTMLDirective(<config...>);
const rawHtml = '<span style="color: red">Hello!</span>';
</script>
In your Nuxt folder, create a new plugin plugins/dompurify-html.ts
with the following content:
import VueDOMPurifyHTML from 'vue-dompurify-html';
export default defineNuxtPlugin((nuxtApp) => {
nuxtApp.vueApp.use(VueDOMPurifyHTML);
});
You can use the same configuration options than the Vue setup. You can see a complete example with some advanced configuration in the Nuxt 3 example.
Note: due to current limitations, the content processed by the directive are only processed client side.
