The WooCommerce Upload Files WordPress plugin before 59.4 ran a single sanitization pass to remove blocked extensions such as .php. It was possible to bypass this and upload a file with a PHP extension by embedding a "blocked" extension within another "blocked" extension in the "wcuf_file_name" parameter. It was also possible to perform a double extension attack and upload files to a different location via path traversal using the "wcuf_current_upload_session_id" parameter.

The WooCommerce Support Ticket System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_tmp_uploaded_file() function in all versions up to, and including, 17.7. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The WooCommerce Support Ticket System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_uploaded_file() function in all versions up to, and including, 17.7.

The WordPress User Extra Fields plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the ajax_save_fields() function in all versions up to, and including, 16.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to add custom fields that can be updated and then use the check_and_overwrite_wp_or_woocommerce_fields function to update the wp_capabilities field to have administrator privileges.

The WooCommerce Upload Files plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the upload_files() function in all versions up to, and including, 84.3.

This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary posts, and read names, emails, and capabilities of all users.

The WooCommerce Customers Manager WordPress plugin before 29.8 does not sanitise and escape various parameters before outputting them back in pages and attributes, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

The WooCommerce Customers Manager WordPress plugin before 30.2 does not have authorisation and CSRF in various AJAX actions, allowing any authenticated users, such as subscriber, to call them and update/delete/create customer metadata, also leading to Stored Cross-Site Scripting due to the lack of escaping of said metadata values.
