Information Exposure

matrix-appservice-irc is an An IRC Bridge for Matrix

Affected versions of this package are vulnerable to Information Exposure due to improper verification of user permissions before constructing a reply to an event. An attacker can leak the truncated body of a message by sending a Matrix reply to an event ID they do not have access to.

Note: This works if the attacker knows the event ID and is joined to both the Matrix room and the IRC channel it is bridged to.
