Issue Summary

Endpoint "rest/config/1.0/directory" can be accessed anonymously. This page is an XML output that exposes the gadgets installed on the Jira instance.

While there are not be any identifying information, user data, or anything else available to anonymous users if they hit this URL, a potential bad actor could better understand which add-ons customers have installed into theirJira instance and use that information to their advantage to attack them. This could be through malicious attacks that exploit those add-ons specifically, taking advantage of possible security vulnerabilities of those instances, or phishing-like attacks where the bad actor may impersonate vendors to get information from us.
