Overview

Affected versions of this package are vulnerable to Improper Access Control due to improper enforcement of Content Security Policy (CSP) directives. An attacker can bypass CSP restrictions by embedding a child iframe with the unsafe-inline directive, which could allow the parent page's CSP to override the child's CSP.
