Goodbye CSS Modules, Hello TailwindCSS
Our frontend codebase is a single-page application powered by Create React App (CRA), written in TypeScript, and using GraphQL for the API. The existing styling approach used CSS Modules without a design system. CSS Modules are CSS files in which all class and animation names are scoped locally by default. They get compiled as part of the build step—with bundler technology like Webpack—and are nat
Web Mitigation Metrics
§ Content Security Policy We believe that a carefully-crafted Content Security Policy can help protect web applications from injection attacks that would otherwise lead to script execution. Strict CSP is a reasonable approach, one which we'd like to encourage. The data below is gathered from Chrome's usage statistics, and represents the percentage of Chrome page loads that use CSP at all, that def
Security headers quick reference  | Articles  | web.dev
Before diving into security headers, learn about known threats on the web and why you'd want to use these security headers. Protect your site from injection vulnerabilities Injection vulnerabilities arise when untrusted data processed by your application can affect its behavior and, commonly, lead to the execution of attacker-controlled scripts. The most common vulnerability caused by injection bu
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

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

GitHub - WICG/csp-next: A Modest Content Security Proposal
Mike West, July 2019 TL;DR: Let's break CSP in half and throw away some options while we're at it. Content Security Policy is a thing. We've been iterating on it for years and years now, and it shows. The backwards compatibility constraints are increasingly contorted, we've moved right past scope creep into scope kudzu, and the implementation status between browsers is inconsistent at best. I thin
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
Bypassing CSP with policy injection
Published: 05 June 2019 at 13:10 UTC Updated: 04 September 2020 at 14:31 UTC Whilst testing PayPal looking for ways to bypass CSP and mixed content protection I found an interesting behaviour. PayPal was putting a GET parameter called token inside the report-uri directive of their CSP. I found that by changing the token parameter it was possible to inject directives into the policy. Most browsers
