CVE NOT AVAILABLE CWE-284  (opens in a new tab)

How to fix?

Upgrade AngularJS.Core to version 1.5.9 or higher.

Overview

AngularJS.Core is an AngularJS.* package for other Angular modules within .NET.

Affected versions of this package are vulnerable to Content Security Policy (CSP) Bypass. Extension URIs (resource://...) bypass Content-Security-Policy in Chrome and Firefox and can always be loaded. Now if a site already has a XSS bug, and uses CSP to protect itself, but the user has an extension installed that uses Angular, an attacker can load Angular from the extension, and Angular's auto-bootstrapping can be used to bypass the victim site's CSP protection.
