Name of the Vulnerable Software and Affected Versions Mailvelope versions prior to 3.1.0

Description The issue allows for a clickjacking attack against the settings page. Since the settings page is meant to be accessible from web applications, the browser's extension isolation mechanisms are disabled. Although Mailvelope has additional measures in place to prevent direct embedding of the settings page by web applications, these measures can be bypassed.

Recommendations For versions prior to 3.1.0, update to version 3.1.0 or later to resolve the issue.
