Amendment
This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Incorrect Permission Assignment for Critical Resource via the openExternal. An attacker can cause an OS-registered external application to be launched by sending requests from sandboxed iframes that are not properly restricted.
Note: This is only exploitable if untrusted content is rendered in sandboxed iframes and the openExternal permission is granted (which is the default unless a custom permission handler is installed).
Workaround
This vulnerability can be mitigated by installing a setPermissionRequestHandler that denies the openExternal permission for untrusted content.
