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
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

H5SC Minichallenge 3: "Sh*t, it's CSP!"
Welcome to yet another XSS challenge. This time, you, the fellow contestant, are confronted with a powerful adversary: The Content Security Policy. CSP is cool. Even if the websites in scope are injectable, an attacker cannot do no nothing no more. Perfect. Let's throw escaping, encoding and filtering overboard because the magic headers will protect us! Yay :D But is CSP really that powerful? Will
