means To escape or allow escape through an unintended opening — a liquid, gas, or secret slipping out where it shouldn't.

from Leak traces back to Old Norse 'leka' (to drip or leak) and is closely related to Old English and Dutch 'lekken.' It's a sturdy, old Germanic word for water finding its way through a hull or roof — the sense of secrets 'leaking out' is a natural metaphorical extension, first clearly documented in English by the 16th-17th century, when information started being talked about as if it, too, could seep through a crack.
