What the vulnerability does
The WordPress User Extra Fields 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, 16.6. 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).
Explanation of Vulnerability in Simple Terms
The WordPress User Extra Fields plugin through version 16.6 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files from the server. An attacker can access sensitive files such as configuration files, database credentials, and other protected data without needing to log in or interact with a user. This vulnerability affects all installations of the plugin up to and including version 16.6.
What an attacker can do
Read arbitrary files from the server, including configuration files and sensitive data.
Potential impact on your site
Attackers can access wp-config.php, database credentials, and other sensitive files without authentication.
Conditions required to exploit
