Affecting angular package, versions <1.6.1

Do your applications use this vulnerable package? Test your applications

Overview

angular is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications with the goal of making development and testing easier by augmenting browser-based applications with model–view–controller (MVC) capability.

Affected versions of the package are vulnerable to JSONP Callbacks attacks.

JSONP (JSON with padding) is a method used to request data from a server residing in a different domain than the client.

Any url could perform JSONP requests, allowing full access to the browser and the JavaScript context. This can lead to Cross-site Scripting.

Remediation

Upgrade angular to version 1.6.1 or higher.
