Summary
Events are missing sender information
Vulnerability Details
When an action is triggered based on a user's action,
not being able to filter based on who triggered the
action makes event processing a lot more cumbersome.
Including the msg.sender the events of these types
of action will make events much more useful to end users,
especially when msg.sender is not tx.origin.
