CVE-2026-27347Network attack vector

Unauthenticated popup disclosure via missing capability check

Published Sep 4, 2026 · Updated Sep 4, 2026

Missing authorization in Crocoblock JetPopup 2.0.20.2 and earlier allows remote attackers to read non-published popup content. The popup-content retrieval path returns non-published popups without enforcing the WordPress read_post capability. A network request requires no account or user interaction; the published assessment identifies content disclosure, not modification or service interruption.
