CVE-2024-6590Network attack vector

Subscriber-level settings modification via unchecked AJAX handlers

Published Sep 25, 2024 · Updated Apr 8, 2026

Missing authorization in WPGSI 3.8.0 and earlier allows remote authenticated users to alter post status and Google Sheets integrations. Four referenced AJAX handlers in class-wpgsi-admin.php process status changes and integration creation without verifying the caller's capability. Subscriber-level access is sufficient, and successful requests can modify stored site and integration data.
