CVE-2025-27282 is a security vulnerability identified in the rockgod100 Theme File Duplicator WordPress plugin, specifically affecting versions up to and including 1.3. The vulnerability is characterized as an 'Unrestricted Upload of File with Dangerous Type,' meaning the plugin fails to properly validate or restrict the types of files that can be uploaded by users. This weakness allows an attacker to upload malicious files, such as web shells or scripts, which can then be executed on the server hosting the WordPress site. The lack of file type restrictions can lead to severe consequences including remote code execution, unauthorized access, data theft, or complete site takeover. The vulnerability was reserved in February 2025 and published in April 2025, with no CVSS score assigned yet. No known exploits have been reported in the wild, but the nature of the vulnerability suggests it could be exploited by unauthenticated attackers if the plugin is publicly accessible. The plugin is used to duplicate theme files within WordPress environments, and improper handling of file uploads is a common attack vector in web applications. The absence of patch links indicates that a fix may not yet be available, increasing the urgency for administrators to apply workarounds or disable the plugin until remediation is provided.

The unrestricted upload vulnerability in Theme File Duplicator can have severe impacts on affected organizations. Attackers could upload malicious scripts or web shells, leading to remote code execution and full compromise of the WordPress site and potentially the underlying server. This can result in data breaches, defacement, loss of service, and use of the compromised server as a pivot point for further attacks within an organization's network. Confidentiality is at risk due to potential data exposure, integrity can be compromised by unauthorized changes, and availability may be affected if the site is defaced or taken offline. The ease of exploitation, given no authentication or user interaction requirements, increases the threat level. Organizations relying on this plugin for theme management are particularly vulnerable, especially if they have not implemented additional security controls such as web application firewalls or file upload restrictions. The lack of known exploits in the wild suggests the vulnerability is newly disclosed, but attackers may develop exploits rapidly given the straightforward nature of the flaw.

Organizations should immediately audit their WordPress installations for the presence of the Theme File Duplicator plugin and its version. If version 1.3 or earlier is detected, the plugin should be disabled or removed until a patch is released. In the absence of an official patch, administrators can implement manual mitigations such as restricting file upload permissions at the server level, configuring web application firewalls (WAFs) to block suspicious file uploads, and enforcing strict MIME type and extension checks. Monitoring upload directories for unexpected file types and scanning for web shells can help detect exploitation attempts. Additionally, limiting access to the plugin’s upload functionality to trusted and authenticated users reduces risk. Regular backups and incident response plans should be updated to prepare for potential compromise. Organizations should subscribe to vendor or security mailing lists to receive updates on patches or further advisories related to this vulnerability.
