## Description

The Store Builder & Product Blocks for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure via the editor search REST endpoint (/wopb/v1/search) in versions 2.6.0 up to, and including, 4.6.2 due to the endpoint querying whatever post type is supplied in the 'condition' parameter (for the 'postExclude', 'productInclude' and 'productExclude' search types) without restricting it to public post types or checking whether the user may read the returned posts. This makes it possible for authenticated attackers, with contributor-level access and above, to list the IDs and titles of published posts of any post type, including non-public types such as WooCommerce coupons, whose titles are the coupon codes.
