Description
The ContentStudio plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the cstu_update_post() function in all versions up to, and including, 1.3.7. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE-2025-67910 is likely a duplicate of this.

Executive Summary

The vulnerability in the ContentStudio plugin for WordPress allows authenticated users with Author-level access or higher to upload arbitrary files to the server because the plugin does not properly validate file types in the cstu_update_post() function. This can potentially lead to remote code execution on the affected site.

Impact Analysis

This vulnerability can allow attackers with Author-level access to upload malicious files to your server, which may lead to remote code execution. This can compromise the security and integrity of your website and server, potentially resulting in data breaches, defacement, or further exploitation.

Mitigation Strategies

To mitigate this vulnerability, immediately update the ContentStudio WordPress plugin to version 1.4.0 or later, as versions up to and including 1.3.7 are vulnerable. Additionally, restrict Author-level access and above to trusted users only, and consider disabling or removing the plugin until a secure version is confirmed. Ensure your WordPress and PHP versions meet the plugin requirements (WordPress 5.8+ and PHP 7.4+). [1]
