Descriptions

The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled. This vulnerability affects Firefox ESR < 45.6 and Firefox < 50.1.

El botón de la barra de herramientas Pocket, una vez se activa, escucha eventos lanzados desde sus propias páginas, pero no verifica el origen de los eventos entrantes. Esto permite que el contenido de otros orígenes lance eventos e inyecte contenido y comandos en el contexto de Pocket. Nota: este problema no afecta a usuarios que tengan e10s habilitado. La vulnerabilidad afecta a Firefox ESR en versiones anteriores a la 45.6 y Firefox en versiones anteriores a la 50.1.
