express-sanitized v0.5.1

express-sanitized

Installation

npm install express-sanitized

Usage

Place this directly after express.bodyParser() and before any request parameters are used, e.g.:

var express = require('express'),
    expressSanitized = require('express-sanitized');

app.use(express.bodyParser());
app.use(expressSanitized()); // this line follows express.bodyParser()

Output

The string

'<script>document.write('cookie monster')</script> download now'

will be sanitized to ' download now'.

Limitations

This is a basic implementation of Caja-HTML-Sanitizer with the specific purpose of mitigating against persistent XSS risks.

Caveats

This module trusts the dependencies to provide basic persistent XSS risk mitigation. A user of this package should review all packages and make their own decision on security and fitness for purpose.

This module was inspired by express-sanitizer. The difference here is strict laziness. This middleware automatically sanitizes post and query values whereas that module requires you to manually sanitize each parameter.
