Mitigate cross-site scripting (XSS) with a strict Content Security Policy (CSP)  | Articles  | web.dev
Cross-site scripting (XSS), the ability to inject malicious scripts into a web app, has been one of the biggest web security vulnerabilities for over a decade. Content Security Policy (CSP) is an added layer of security that helps to mitigate XSS. To configure a CSP, add the Content-Security-Policy HTTP header to a web page and set values that control what resources the user agent can load for tha
Chrome extension compiled by Webpack throws `unsafe-eval` error
I get this error when reloading my Chrome Extension after compiling using Webpack: Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:". at new Function (<anonymous>) at evalExpression (compiler.js:33919) at jitState
How To Secure Node.js Applications with a Content Security Policy | DigitalOcean
The author selected the Free Software Foundation to receive a donation as part of the Write for DOnations program. Introduction When the browser loads a page, it executes a lot of code to render the content. The code could be from the same origin as the root document, or a different origin. By default, the browser does not distinguish between the two and executes any code requested by a page regar
Collection of CSP bypasses
Collection of CSP bypasses On this page, I'd like to collect a set of CSP bypasses related to nonces. CSP policies using nonces are considered very strong in terms of security. However, there are many (sometimes unusual) situations in which nonces can be bypassed. It is still unclear to me, if these bypasses have a practical impact on CSP's protective capabilities. Nevertheless, I'd like to explor
CSP Evaluator
CSP Evaluator allows developers and security experts to check if a Content Security Policy (CSP) serves as a strong mitigation against cross-site scripting attacks. It assists with the process of reviewing CSP policies, which is usually a manual task, and helps identify subtle CSP bypasses which undermine the value of a policy. CSP Evaluator checks are based on a large-scale study and are aimed to
Introduction - Content Security Policy
This documentation is outdated and available for historical reasons only. To learn how to enable strict Content Security Policy in your application, visit web.dev/strict-csp. Content Security Policy is a mechanism designed to make applications more secure against common web vulnerabilities, particularly cross-site scripting. It is enabled by setting the Content-Security-Policy HTTP response header
