Description
A security issue has been found in Firefox < 64.0, where limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to opened privileged about: or file: locations.
