No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
Affected versions of event-listener unconditionally implement Send and Sync for StackSlot<' , T>, the stack-allocated listener type created by the listener! macro.
This allows a !Send tag type set via Event::with tag to be moved to another thread and accessed via StackSlot::wait, causing a data race in safe code.
