Actual results:

Modifications are not allowed for this document

Removes the data of the specified formats. Removes all data if the argument is omitted.
Component: Untriaged → DOM
Product: Firefox → Core
This doesn't look like a security issue to me.
Component: DOM → Drag and Drop
Keywords: html5
The actual expected result is that nothing should happen. clearData only has any effect during dragstart. We throw an exception because this was implemented before the spec said much about what to do in this case.
Summary: clearData → user event.dataTransfer.clearData in ondragend doesn't allow modifications
