SCA: security update for matrix-react-sdk (GHSA-xv83-x443-7rmw)

medium Tenable Cloud Security Plugin ID 420674

Description

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

 - matrix-react-sdk is a react-based SDK for inserting a Matrix chat/VoIP client into a web page. Prior to
 version 3.71.0, plain text messages containing HTML tags are rendered as HTML in the search results. To
 exploit this, an attacker needs to trick a user into searching for a specific message containing an HTML
 injection payload. No cross-site scripting attack is possible due to the hardcoded content security
 policy. Version 3.71.0 of the SDK patches over the issue. As a workaround, restarting the client will
 clear the HTML injection. (CVE-2023-30609)
