Kingdom: Security Features
Software security is not security software. Here we're concerned with topics like authentication, access control, confidentiality, cryptography, and privilege management.
HTML5: Insecure Cross-Origin Opener Policy
Abstract
The program defines an overly permissive Cross-Origin Opener Policy (COOP)
Explanation
It has become important to enforce the data privacy of a given web document due to the existance of side-channel exploits that result from vulnerabilities such as Spectre and Meltdown. The Cross-Origin Opener Policy (COOP) was created to help prevent sensitive information exposure due to side-channel attacks. Specifically, the COOP can enforce isolation of a document's browsing context group in regard to other external documents, such as popups.
Example 1: The following code shows an unsecure COOP setting of 'unsafe-none' in the Django framework. This might allow an external document to access the private data of a source document's browsing context group due to a side-channel attack.
