SCA: security update for matrix-appservice-irc (GHSA-3pmj-jqqp-2mj3)

critical Tenable Cloud Security Plugin ID 409632

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it is possible to craft
 a command with newlines which would not be properly parsed. This would mean you could pass a string of
 commands as a channel name, which would then be run by the IRC bridge bot. Versions 1.0.1 and above are
 patched. There are no robust workarounds to the bug. One may disable dynamic channels in the config to
 disable the most common execution method but others may exist. (CVE-2023-38690)
