CodiMD 1.3.1, when Safari is used, allows XSS via an IFRAME element with allow-top-navigation in the sandbox attribute, in conjunction with a data: URL.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
