The plugin exposes two AJAX handlers that, when combined, allow any authenticated user to modify admin-level plugin settings. First, the wc_rb_get_fresh_nonce() function (registered via wp_ajax and wp_ajax_nopriv hooks) allows any user to generate a valid WordPress nonce for any arbitrary action name by simply providing the nonce_name parameter, with no capability checks. Second, the wc_rep_shop_settings_submission() function only verifies the nonce (wcrb_main_setting_nonce) but performs no current_user_can() capability check before updating 15+ plugin options via update_option(). This makes it possible for authenticated attackers, with subscriber-level access and above, to modify all plugin configuration settings including business name, email, logo, menu label, GDPR settings, and more by first minting a valid nonce via the wc_rb_get_fresh_nonce endpoint and then calling the settings submission handler."}, {"lang": "es", "value": "El plugin RepairBuddy \u2013 Repair Shop CRM & Booking para WordPress es vulnerable a acceso no autorizado en todas las versiones hasta, e incluyendo, la 4.1132.
