Security News > 2020 > December > Google Launches XS-Leaks Vulnerability Knowledge Base

Google this week announced the launch of a knowledge base with information on a class of vulnerabilities referred to as cross-site leaks, or XS-Leaks.

These vulnerabilities, Google explains, are rooted in the modern web applications' misuse of long-standing web platform behaviors, thus resulting in websites leaking information on the user or the information the user has entered in other web applications.

Google invites security researchers to help expand the wiki and to share details on new attacks and defenses.

The wiki is also meant to help web developers understand how the defense mechanisms within browsers can keep their applications protected from cross-site leaks.

"Each attack described in the wiki is accompanied by an overview of security features which can thwart or mitigate it; the wiki aims to provide actionable guidance to assist developers in the adoption of new browser security features such as Fetch Metadata Request Headers, Cross-Origin Opener Policy, Cross-Origin Resource Policy, and SameSite cookies," Google explains.
