SCA: security update for atlassian-connect-express (GHSA-4v96-m8xv-x83v)

high Tenable Self-Hosted Container Security Plugin ID 422717

Description

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

 - Broken Authentication in Atlassian Connect Express (ACE) from version 3.0.2 before version 6.6.0:
 Atlassian Connect Express is a Node.js package for building Atlassian Connect apps. Authentication between
 Atlassian products and the Atlassian Connect Express app occurs with a server-to-server JWT or a context
 JWT. Atlassian Connect Express versions from 3.0.2 before 6.6.0 erroneously accept context JWTs in
 lifecycle endpoints (such as installation) where only server-to-server JWTs should be accepted, permitting
 an attacker to send authenticated re-installation events to an app. (CVE-2021-26073)
