Advisory
Source description from Wordfence Intelligence, credited to chaeyp, Ronnachai Sretawat Na Ayutaya (Simonhaskelly), Ronnachai Chaipha (rxnr).
The RepairBuddy – Repair Shop CRM & Booking Plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 4.1132. 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.
