Name of the Vulnerable Software and Affected Versions matrix-appservice-irc versions prior to 1.0.1

Description The issue allows an attacker to craft a command with newlines that would not be properly parsed, enabling them to pass a string of commands as a channel name, which would then be executed by the IRC bridge bot.

Recommendations For versions prior to 1.0.1, upgrade to version 1.0.1 or above to resolve the issue. As a temporary workaround, consider disabling dynamic channels in the config to disable the most common execution method.
