Cross-site leaks
Class of web security attacks
Cross-site leaks, also known as XS-leaks, is an internet security term used to describe a class of attacks used to access a user's sensitive information on another website. Cross-site leaks allow an attacker to access a user's interactions with other websites. This can contain sensitive information. Web browsers normally stop other websites from seeing this information. This is enforced through a set of rules called the same-origin policy. Attackers can sometimes get around these rules, using a "cross-site leak". Attacks using a cross-site leak are often initiated by enticing users to visit the attacker's website. Upon visiting, the attacker uses malicious code on their website to interact with another website. This can be used by a attacker to learn about the user's previous actions on the other website. The information from this attack can uniquely identify the user to the attacker.
