CVE-2025-5393: Alone WordPress Theme RCE Vulnerability

CVE-2025-5393 Overview

The Alone – Charity Multipurpose Non-profit WordPress Theme for WordPress contains a critical arbitrary file deletion vulnerability due to insufficient file path validation in the alone_import_pack_restore_data() function. This vulnerability affects all versions up to and including 7.8.3, allowing unauthenticated attackers to delete arbitrary files on the server. When critical files such as wp-config.php are deleted, this can easily lead to remote code execution.

Critical Impact

Unauthenticated attackers can delete arbitrary files on vulnerable WordPress installations, potentially leading to complete site compromise and remote code execution.

Affected Products

• Alone – Charity Multipurpose Non-profit WordPress Theme versions up to and including 7.8.3
• WordPress installations using the vulnerable theme

Technical Details for CVE-2025-5393

Vulnerability Analysis

This vulnerability is classified under CWE-73 (External Control of File Name or Path), which occurs when software allows user input to control or influence file system paths without proper validation. The alone_import_pack_restore_data() function in the Alone WordPress theme fails to adequately validate file paths provided by users, enabling path traversal attacks that can target any file accessible to the web server process.

The critical nature of this flaw stems from its accessibility to unauthenticated users, meaning no login credentials or WordPress account is required to exploit this vulnerability. An attacker can craft malicious requests to delete configuration files, plugin files, or even core WordPress files, disrupting site functionality and potentially enabling follow-up attacks.

Root Cause

The root cause is insufficient file path validation within the alone_import_pack_restore_data() function. The function accepts user-supplied input that specifies file paths but does not properly sanitize or restrict this input to safe directories. This allows attackers to use directory traversal sequences (such as ../) to escape the intended directory and target arbitrary files on the file system.

Attack Vector

The attack is executed over the network without requiring authentication. An attacker can send specially crafted HTTP requests to a WordPress site running the vulnerable Alone theme. By manipulating the file path parameter in requests to the import/restore functionality, the attacker can specify paths to sensitive files outside the intended scope.

The exploitation process typically involves:

1. Identifying a WordPress installation using the Alone theme version 7.8.3 or earlier
2. Crafting a malicious request to the alone_import_pack_restore_data() function endpoint
3. Including path traversal sequences to target critical files like wp-config.php
4. Upon deletion of wp-config.php, the WordPress installation enters setup mode, allowing the attacker to reconfigure the site with their own database and credentials

Detection Methods for CVE-2025-5393

Indicators of Compromise

• Unexpected deletion of critical WordPress files such as wp-config.php, .htaccess, or plugin files
• WordPress site entering installation/setup mode unexpectedly
• Web server logs showing unusual requests to theme-related AJAX endpoints with path traversal patterns
• File system integrity monitoring alerts for deleted configuration files

Detection Strategies

• Monitor web server access logs for requests containing path traversal sequences (../, ..%2f, etc.) targeting theme endpoints
• Implement file integrity monitoring to detect unexpected deletion of critical WordPress files
• Deploy web application firewall (WAF) rules to block requests with directory traversal patterns
• Review AJAX handler requests to the Alone theme's import/restore functionality for anomalous patterns

Monitoring Recommendations

• Enable detailed logging for WordPress AJAX requests and theme function calls
• Configure alerts for deletion events on critical WordPress configuration files
• Implement real-time monitoring of file system changes in the WordPress installation directory
• Use SentinelOne's Singularity platform to detect and respond to file deletion activities indicative of exploitation

How to Mitigate CVE-2025-5393

Immediate Actions Required

• Update the Alone – Charity Multipurpose Non-profit WordPress Theme to a version newer than 7.8.3 immediately
• If an update is not available, consider temporarily deactivating the theme until a patch is released
• Implement WAF rules to block requests containing path traversal patterns targeting theme endpoints
• Verify the integrity of critical WordPress files including wp-config.php and core files

Patch Information

Check the ThemeForest WordPress Theme page for the latest version and security updates. Ensure automatic theme updates are enabled or manually update to the patched version as soon as it becomes available.

Workarounds

• Deploy a web application firewall with rules to filter path traversal attempts in request parameters
• Restrict file system permissions so the web server process cannot delete critical configuration files
• Implement server-level file immutability flags on essential files like wp-config.php using chattr +i on Linux systems
• Monitor and back up critical configuration files regularly to enable rapid recovery

# Make wp-config.php immutable to prevent deletion (Linux servers)
chattr +i /var/www/html/wp-config.php

# Verify immutable attribute is set
lsattr /var/www/html/wp-config.php
