What the vulnerability does
The WP User Frontend Pro plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_avatar_ajax() function in all versions up to, and including, 4.1.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, 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
WP User Frontend Pro versions up to 4.1.3 contain a path traversal vulnerability that allows authenticated users to read, modify, or delete arbitrary files on the server. An attacker with low-level user access can bypass file restrictions and access sensitive data outside the intended upload directories. This affects file integrity and availability on affected sites.
What an attacker can do
Read, modify, or delete arbitrary files on the server outside intended directories.
Potential impact on your site
Attackers with user accounts can compromise file integrity, delete critical files, or expose sensitive configuration data.
Conditions required to exploit
Attacker must have a low-privilege user account (e.g., subscriber or contributor role) on the site.
