Overview
The Alone – Charity Multipurpose Non-profit WordPress Theme has been discovered to have a critical vulnerability, CVE-2025-5393, that affects all versions of the theme up to, and including, version 7.8.3. This vulnerability allows unauthenticated attackers to delete arbitrary files on the server, which can lead to remote code execution when a crucial file such as the wp-config.php is deleted. Given the widespread usage of WordPress and the theme in question, this vulnerability presents a significant risk to a large number of websites and their underlying systems.

How the Exploit Works
This vulnerability stems from the lack of proper file path validation in the alone_import_pack_restore_data() function. An attacker can manipulate the file path in the function to delete any file on the server. If a critical file such as wp-config.php is deleted, it could lead to remote code execution, allowing the attacker to execute arbitrary code or commands on the server.
Conceptual Example Code
Though it would be unethical and potentially illegal to provide actual exploit code, a conceptual example would look something like this:
POST /wp-admin/admin-ajax.php?action=alone_import_pack_restore_data HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "file": "../../../../../../etc/passwd" }In this conceptual example, the malicious payload is designed to trick the server into deleting the /etc/passwd file, a critical file on Unix-based systems.
Impact and Mitigation
A successful exploitation of this vulnerability could lead to system compromise or data leakage. As the vulnerability allows for arbitrary file deletion, an attacker could potentially delete any file on the server. This could lead to significant disruption of the website, data loss or even complete system takeover if the right files are deleted.
As for mitigation, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as temporary mitigation by blocking malicious traffic attempting to exploit this vulnerability.
