Summary
The PPOM plugin (Product Addons & Custom Fields for WooCommerce) for WordPress by themeisle is affected in all versions up to and including 34.0.10. Insufficient file path validation in the rename_files function (CWE-22) lets an unauthenticated remote attacker delete arbitrary files on the server. Deleting a file such as wp-config.php can lead to remote code execution, and the relocated file becomes readable in a publicly accessible uploads directory.

Description from the CNA
The PPOM – Product Addons & Custom Fields for WooCommerce plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the rename_files function in all versions up to, and including, 34.0.10 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 relocated file is moved byte-identically into the publicly accessible wp-content/uploads/ppom_files/confirmed/ directory, meaning the attack also results in arbitrary file read for any web-readable file on the server.
