Subscriber data compromise via unchecked AJAX handlers
Published Mar 26, 2025 · Updated Apr 8, 2026
Missing authorization in WP Compress 6.30.15 and earlier allows remote authenticated users to read, alter, or delete plugin data. Multiple AJAX handlers in classes/ajax.class.php perform sensitive settings and configuration operations without checking the caller's WordPress capabilities. A Subscriber account is sufficient; successful abuse exposes settings and can modify or delete configuration, disrupting plugin operation.
