SCA: security update for matrix-appservice-irc (GHSA-cq7q-5c67-w39w)

medium Tenable Cloud Security Plugin ID 414022

Description

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

 - matrix-appservice-irc is an open source Node.js IRC bridge for Matrix. The Internet Relay Chat (IRC)
 protocol allows you to specify multiple modes in a single mode command. Due to a bug in the underlying
 matrix-org/node-irc library, affected versions of matrix-appservice-irc perform parsing of such modes
 incorrectly, potentially resulting in the wrong user being given permissions. Mode commands can only be
 executed by privileged users, so this can only be abused if an operator is tricked into running the
 command on behalf of an attacker. The vulnerability has been patched in matrix-appservice-irc 0.35.0. As a
 workaround users should refrain from entering mode commands suggested by untrusted users. Avoid using
 multiple modes in a single command. (CVE-2022-39202)
