Summary
matrix-appservice-irc events can be crafted to leak parts of targeted messages from other bridged rooms
Details

matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it was possible to craft an event such that it would leak part of a targeted message event from another bridged room. This required knowing an event ID to target. Version 1.0.1n fixes this issue. As a workaround, set the matrixHandler.eventCacheSize config value to 0. This workaround may impact performance.
