Description
The RepairBuddy – Repair Shop CRM & Booking Plugin for WordPress plugin for WordPress is vulnerable to unauthorized deletion and modification of data via the Devices & Services AJAX actions (such as crs_delete_device, crs_save_device_model and crs_save_service_row) in all versions up to, and including, 4.1235. This is due to missing capability checks and missing post type validation: the handlers relied only on the 'crs_devices_nonce' nonce, which is printed on a Devices & Services management page that any user with the 'delete_posts' capability can open. This makes it possible for authenticated attackers, with Contributor-level access and above, to permanently delete arbitrary posts (including pages, products and orders), rename arbitrary posts, and change service price and status metadata.
