SCA: security update for matrix-appservice-irc (GHSA-xvqg-mv25-rwvw)
high Tenable Self-Hosted Container Security Plugin ID 420689
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. 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.enabled` to 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. (CVE-2022-39203)
