What are fetch metadata request headers and how can they be used to differentiate between same origin and cross-site requests?
Fetch metadata request headers are a set of HTTP headers that can be used to provide additional information about a request in web applications. These headers can play a crucial role in differentiating between same origin and cross-site requests, thereby enhancing the security of web applications. In this explanation, we will delve into the concept
How do trusted types reduce the attack surface of web applications and simplify security reviews?
Trusted types are a modern platform feature that can significantly enhance the security of web applications by reducing the attack surface and simplifying security reviews. In this answer, we will explore how trusted types achieve these objectives and discuss their impact on web application security. To understand how trusted types reduce the attack surface of
What is the purpose of the default policy in trusted types and how can it be used to identify insecure string assignments?
The purpose of the default policy in trusted types is to provide an additional layer of security for web applications by enforcing strict rules on string assignments. Trusted types is a modern platform feature that aims to mitigate various types of vulnerabilities, such as cross-site scripting (XSS) attacks, by preventing the execution of untrusted code.

How does the trusted types directive in a content security policy help mitigate DOM-based cross-site scripting (XSS) vulnerabilities?
The trusted types directive in a content security policy (CSP) is a powerful mechanism that helps mitigate DOM-based cross-site scripting (XSS) vulnerabilities in web applications. XSS vulnerabilities occur when an attacker is able to inject malicious scripts into a web page, which are then executed by the victim's browser. These scripts can be used to
What are trusted types and how do they address DOM-based XSS vulnerabilities in web applications?
Trusted types are a modern platform feature that addresses DOM-based Cross-Site Scripting (XSS) vulnerabilities in web applications. DOM-based XSS is a type of vulnerability where an attacker injects malicious code into a web page, which is then executed by the victim's browser. This can lead to various security risks, such as stealing sensitive information, performing
