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 stepâ€”with bundler techno logy like Webpackâ€”and are nat

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

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.
