CVE-2024-26138 – License information is public, exposing instance id and license holder details

https://notcve.org/view.php?id=CVE-2024-26138

The XWiki licensor application, which manages and enforce application licenses for paid extensions, includes the document `Licenses.Code.LicenseJSON` that provides information for admins regarding active licenses. This document is public and thus exposes this information publicly. The information includes the instance's id as well as first and last name and email of the license owner. This is a leak of information that isn't supposed to be public. The instance id allows associating data on the active installs data with the concrete XWiki instance. • https://extensions.xwiki.org/xwiki/bin/view/Extension/Active%20Installs%202%20API https://github.com/xwikisas/application-licensing/commit/d168fb88fc0d121bf95e769ea21c55c00bebe5a6 https://github.com/xwikisas/application-licensing/security/advisories/GHSA-4hfp-m9gv-m753 • CWE-862: Missing Authorization •
