CVE-2026-27091Network attack vector

Subscriber-level unauthorized actions

Published Mar 19, 2026 · Updated Mar 19, 2026

Missing authorization in UiPress lite 3.5.09 and earlier allows remote authenticated users to perform unauthorized actions over the network. An affected function processes a privileged request without a WordPress capability check, but published sources do not identify the function or action. Subscriber-level access is sufficient, and the published assessment bounds the consequence to limited confidentiality, integrity, and availability effects.
