Overview
The world of cybersecurity is in a constant state of change and adaptation. One significant vulnerability that has recently caught our attention is CVE-2025-7643. This vulnerability affects the Attachment Manager plugin for WordPress, used widely by businesses and individuals to manage their website files. It’s a crucial issue because it exposes an avenue for unauthenticated attackers to delete arbitrary files on the server. The consequences could be severe, leading to remote code execution when the wrong file is deleted.

How the Exploit Works
The vulnerability lies within the handle_actions() function of the Attachment Manager plugin for WordPress. This function lacks sufficient file path validation, which allows an attacker to manipulate the file path and delete arbitrary files on the server. The issue is even more critical as it does not require any authentication, meaning any potential attacker can exploit it. If a critical file like wp-config.php is deleted, it can easily pave the way for remote code execution.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This example showcases a malicious HTTP POST request to the vulnerable endpoint.
POST /wp-content/plugins/attachment-manager/handle_actions.php HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "file_path": "/absolute/path/to/wp-config.php" }In this example, the attacker is deleting the wp-config.php file, a fundamental WordPress configuration file. Removing this file can cause significant disruption to the website and potentially allow the attacker to execute remote code.
Mitigation
To mitigate the risk of this vulnerability, apply the vendor provided patch for the WordPress Attachment Manager plugin as soon as possible. If a patch cannot be applied immediately, consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation. Regularly updating and patching your WordPress and its plugins is a recommended practice to ensure your website’s security.
