Cross site leakage, also known as & quot; XS leaks & quot;, is a kind of problem in network design, which allows network applications to interact with each other, even if they are not related. This leads to the sharing of user data between different web applications, which usually leads to serious security vulnerabilities. In order to solve the growing number of security vulnerabilities that rely on cross site leaks, Google announced that it has established a knowledge base so that developers and security researchers can better understand the problem and build defense measures around it. < / P > < p > this knowledge base is called & quot; XS leaks wiki & quot; and contains articles that explain the concept of cross site leakage, demonstrate some common attacks, and introduce the defense measures you set up against them. In addition to the details of each attack, proof of concept code is provided. Another goal of this knowledge base is to help developers understand the various security features provided by browsers to prevent cross site leakage, such as cross source resource policy and samesite cookie. < / P > < p > Google hopes to provide this knowledge base to companies, security researchers and network developers to make the network more secure for all users, based on years of experience provided by all parties concerned, by protecting all users from the threat of using this behavior. < / P > < p > you can learn more about cross site leaks by visiting Google’s dedicated website, which is Google’s dedicated website or the relevant GitHub repository. Google said the proposed media negotiation rules would put its free services in Australia at “risk”
