The WP All Import Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.9.7. This is due to missing nonce validation on the delete_and_edit function. This makes it possible for unauthenticated attackers to delete imported content (posts, comments, users, etc.) via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

The Import any XML or CSV File to WordPress PRO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 4.9.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.

The WP All Import Pro plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.9.3 due to missing SSRF protection on the pmxi_curl_download function. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. On cloud platforms, it might allow attackers to read the Instance metadata.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.
