Subscriber-level configuration manipulation via unchecked AJAX calls
Published Aug 31, 2023 · Updated Apr 8, 2026
Authorization bypass in AJAX calls in Waiting: One-click countdowns 0.6.2 and earlier allows remote authenticated users to alter plugin settings. The AJAX handlers create and delete countdowns and update settings without checking the caller's WordPress capability. Subscriber-level access is sufficient; the documented consequence is unauthorized countdown and configuration changes rather than code execution.
