Description
A flaw was found in Katello where the Flatpak Remote Repositories API does not properly enforce authorization when accessing a flatpak remote repository by identifier. An authenticated user with permission to view flatpak remotes in one organization may be able to access flatpak remote repository information belonging to another organization. The same unscoped lookup is used by the mirror action, which may allow creating a repository in a product the user can edit that is configured with another organization's flatpak remote URL and stored remote credentials.
