Subscriber-level configuration alteration via unchecked save function

Published Jun 9, 2023 · Updated Apr 8, 2026

Missing authorization in WPCS – WordPress Currency Switcher Professional 1.1.9 and earlier allows remote authenticated users to alter switchers. The save function accepts subscriber-controlled requests and updates arbitrary custom drop-down currency-switcher configuration without enforcing an administrative capability check. Any WordPress account with subscriber-level access can alter display configuration, with no published data-disclosure or service-interruption impact.
