CVE-2023-49103ownCloud — the environment dump anyone could fetch

A library bundled with the ownCloud graph app serves a page that prints the web server's whole environment. In container deployments that includes the administrator password, mail credentials and the licence key, and removing the app does not close it.

YOUR NEXT MOVE

Upgrade the graph app to 0.2.1 or 0.3.1, delete the file that prints the environment, then rotate the administrator password, mail credentials and licence key.
