Impact
When an event is emitted based on a user's action, not being able to filter based on the address that triggered the event makes event processing more difficult, particularly when msg.sender is not tx.origin.
Tools Used
baudit: a custom static code analysis tool; manual review
Recommendations
Include msg.sender in user-triggered event emissions.
