CVE-2019-9147
Mailvelope prior to 3.1.0 is vulnerable to a clickjacking attack against the settings page.
MEDIUM 4.3EPSS 1.44%
Does this matter?
Lower severity and a low EPSS score (1.44%). Track it; it rarely justifies an emergency change on its own.
Description
Mailvelope prior to 3.1.0 is vulnerable to a clickjacking attack against the settings page. As the settings page is intended to be accessible from web applications, the browser's extension isolation mechanisms are disabled (web_accessible_resources). Mailvelope implements additional measures to prevent web applications from directly embedding the settings page, but this mechanism can be bypassed.
