Descriptions

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 open privileged about: or file: locations. This vulnerability affects Firefox < 64.

La API browser.windows.create permitía que las WebExtensions omitiesen las limitaciones en las URI cuando una tubería (pipe) en el campo URL se utiliza con la extensión para cargar múltiples páginas como un solo argumento. Esto podría permitir que un WebExtension malicioso abra las ubicaciones privilegiadas about: o file:. Esta vulnerabilidad afecta a las versiones anteriores a la 64 de Firefox.
