Description Huzaifa S. Sidhpurwala 2016-12-13 16:27:38 UTC 
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.
