JarCastingDEPRECATED - OWASP Enterprise Security API for JavaScript (ESAPI-JS)
This file is part of the Open Web Application Security Project (OWASP) Enterprise Security API (ESAPI) project. For details, please see https://owasp.org/www-project-enterprise-security-api/.

WARNING: This project is deprecated and unmaintainted. Use at your own risk.
This project is no longer supported. It is known to be potentially affected by a vulnerability in 'bower' (specifically, CVE-2019-5484). This vulnerability could be addressed by upgrading ESAPI-JS to use bower 1.8.8 or later, however this has been tried and resulted in deployment problems when using NPM. See the ensuing discussion for PR#29 for details.
Potential Alternatives to ESAPI-JS (aka, ESAPI4JS)
- node-esapi - a minimal port of ESAPI-JS' output encoder that does not depend on bower and as of this writing (2021-03-30), has no known vulnerabilities. It does not include the validator or other portions of ESAPI-JS.
- DOMPurify - a DOM-only, XSS sanitizer for HTML, MathML, and SVG.
- Lots of additional alternatives if your project is not pure JavaScript.
Looking for Maintainers
If you would like to support project, please contact one or both of the ESAPI project leaders listed on the OWASP ESAPI wiki page. They can unarchive it for you.
Installation Instructions
$ npm install --save-dev ESAPI-JS
Installation:
- Download the distribution zip from http://owasp-esapi-js.googlecode.com
- Unzip the distribution zip
- Create a directory on your server, under the web root called esapi4js
- Copy either esapi.js or esapi-compressed.js from dist/ to your esapi4js directory
- Create a lib directory under the esapi4js called lib and copy the contents of dist/lib to that directory
- Create a resources directory under the esapi4js called resources and copy the contents of dist/resources to that directory
Quick Start:
<!-- esapi4js dependencies --><script type="text/javascript" language="JavaScript" src="{your_installation_path}/esapi4js/lib/log4js.js"></script>
<!-- esapi4js i18n resources -->

};
Base.esapi.properties.application.Name = "My Application v1.0";
// Initialize the api
org.owasp.esapi.ESAPI.initialize();
// Using the logger
$ESAPI.logger().getLogger('ApplicationLogger').info(org.owasp.esapi.Logger.EventType.EVENT_SUCCESS, 'This is a test message');
// Using the encoder
document.writeln( $ESAPI.encoder().encodeForHTML( "<a href=\"http://owasp-esapi-js.googlecode.com\">Check out esapi4js</a>" ) );
// Using the validator
var validateCreditCard = function() {
return $ESAPI.validator().isValidCreditCard( $('CreditCard').value );
