Description
The WP Ultimate CSV Importer plugin for WordPress is vulnerable to Sensitive Information Exposure via the single post CSV export feature in all versions up to, and including, 9.1. This is due to export files being written to a publicly accessible uploads directory under a predictable name based on the post ID ({post_id}.csv). This makes it possible for unauthenticated attackers to download previously exported CSV files, which contain post content and all post meta, including data from private or draft posts, after an administrator has exported a post.
