What the vulnerability does
The Game Users Share Buttons plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ajaxDeleteTheme() function in all versions up to, and including, 1.3.0. This makes it possible for Subscriber-level attackers to add arbitrary file paths (such as ../../../../wp-config.php) to the themeNameId parameter of the AJAX request, which can lead to remote code execution.
Explanation of Vulnerability in Simple Terms
Game Users Share Buttons versions 1.3.0 and earlier contain a path traversal vulnerability that allows authenticated users to read arbitrary files from the server. An attacker with low-level access can bypass directory restrictions and access sensitive files outside the intended application directory. This affects confidentiality, integrity, and availability of the affected system.
What an attacker can do
Read, modify, or delete arbitrary files on the server outside the intended application directory.
Potential impact on your site
Sensitive files (config, database credentials, private keys) may be exposed, modified, or deleted by authenticated attackers.
Conditions required to exploit
Attacker must have a low-level user account or authenticated session on the site.
