Unauthenticated content disclosure via unchecked REST access
Published Aug 26, 2026 · Updated Aug 26, 2026
Missing authorization in Arraytics Eventin before 4.1.22 allows remote attackers to read unpublished posts through its REST API. One REST API namespace returns draft, pending, private, and password-protected posts without checking publication status or ownership. No authentication is required, and responses expose protected content and post passwords; the namespace and handler name remain undisclosed.
