- Details
-
matrix-appservice-irc is an open source Node.js IRC bridge for Matrix. Attackers can specify a specific string of characters, which would confuse the bridge into combining an attacker-owned channel and an existing channel, allowing them to grant themselves permissions in the channel. The vulnerability has been patched in matrix-appservice-irc 0.35.0. As a workaround operators may disable dynamic channel joining via
dynamicChannels.enabledto prevent users from joining new channels, which prevents any new channels being bridged outside of what is already bridged, and what is specified in the config. - References
