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.
The WooCommerce Customers Manager WordPress plugin before 29.8 does not have authorisation and CSRF in an AJAX action, allowing any authenticated users, such as subscriber, to call it and retrieve the list of customer email addresses along with their id, first name and last name
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 29.7 does not properly sanitise and escape a parameter before using it in a SQL statement, leading to an SQL injection exploitable by Subscriber+ role.
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.
