Stored XSS via unprotected AJAX settings actions
Published May 2, 2022 · Updated Apr 28, 2026
Stored XSS in Cloudways Breeze Cache 2.0.2 and earlier allows remote authenticated users to inject script through plugin settings. Breeze_Configuration exposes its wp_ajax_* settings actions without an adequate capability check, allowing Subscriber accounts to rewrite options such as the CDN URL. Subscriber-level access and a later visit by a privileged user are required; the stored script executes in that visitor's browser and can access data available to that session.
