CVE-2025-30911: RomethemeKit For Elementor RCE Vulnerability

CVE-2025-30911 Overview

CVE-2025-30911 is a critical code injection vulnerability affecting the RomethemeKit For Elementor WordPress plugin. This improper control of code generation (CWE-94) allows authenticated attackers to execute arbitrary commands on vulnerable WordPress installations through command injection. The vulnerability enables arbitrary plugin installation and activation, ultimately leading to remote code execution (RCE) on affected systems.

Critical Impact

Authenticated attackers with low privileges can exploit this vulnerability to achieve full remote code execution on WordPress sites running vulnerable versions of RomethemeKit For Elementor, potentially leading to complete site compromise, data theft, and malware deployment.

Affected Products

• RomethemeKit For Elementor plugin versions up to and including 1.5.4
• WordPress installations using vulnerable RomethemeKit For Elementor versions
• Sites utilizing Elementor page builder with RomethemeKit extensions

Technical Details for CVE-2025-30911

Vulnerability Analysis

This vulnerability stems from improper control of code generation within the RomethemeKit For Elementor plugin. The flaw allows authenticated users to bypass security controls and execute arbitrary commands on the server. The attack can be initiated remotely over the network, requires low attack complexity, and only needs low-privilege authentication. Due to the scope change characteristic, successful exploitation can impact resources beyond the vulnerable component itself, affecting the confidentiality, integrity, and availability of the entire WordPress installation and potentially the underlying server.

Root Cause

The vulnerability exists due to insufficient input validation and improper access controls within the plugin's functionality for handling plugin installations. The RomethemeKit For Elementor plugin fails to properly sanitize user-supplied input before processing plugin installation and activation requests, allowing attackers to inject malicious commands. This represents a classic CWE-94 (Improper Control of Generation of Code) weakness where the application constructs code segments using externally-influenced input without proper neutralization.

Attack Vector

The attack vector is network-based, allowing remote exploitation by authenticated users. An attacker with low-level WordPress privileges (such as a subscriber or contributor role) can exploit this vulnerability through the following mechanism:

1. The attacker authenticates to the WordPress site with minimal privileges
2. The attacker crafts a malicious request targeting the vulnerable plugin installation functionality
3. Through command injection, the attacker can install and activate arbitrary plugins
4. The malicious plugin payload executes arbitrary PHP code on the server
5. Full remote code execution is achieved, allowing complete system compromise

The vulnerability's exploitation does not require user interaction, making it particularly dangerous for websites with open user registration or compromised low-privilege accounts.

Detection Methods for CVE-2025-30911

Indicators of Compromise

• Unexpected plugin installations or activations in the WordPress admin panel
• Unusual PHP files appearing in the wp-content/plugins/ directory
• Suspicious outbound network connections from the WordPress server
• Anomalous user account creation or privilege escalation events
• Web server access logs showing unusual POST requests to RomethemeKit endpoints

Detection Strategies

• Monitor WordPress audit logs for unauthorized plugin installation or activation attempts
• Implement file integrity monitoring on the wp-content/plugins/ directory
• Deploy web application firewall (WAF) rules to detect command injection patterns
• Review PHP error logs for unusual code execution or file operation errors

Monitoring Recommendations

• Enable WordPress debug logging and regularly review logs for suspicious activity
• Configure alerts for any new plugin installations outside of maintenance windows
• Monitor server resource utilization for unexpected spikes indicating malicious activity
• Implement network-level monitoring to detect command and control communications

How to Mitigate CVE-2025-30911

Immediate Actions Required

• Update RomethemeKit For Elementor to a patched version immediately if available
• Audit all WordPress user accounts and remove unnecessary privileges
• Review installed plugins for any unauthorized additions
• Consider temporarily deactivating RomethemeKit For Elementor until a patch is applied
• Implement additional authentication controls for administrative functions

Patch Information

Organizations should check the Patchstack WordPress Vulnerability Database for the latest patch information and remediation guidance. Update to a version higher than 1.5.4 when available from the plugin vendor.

Workarounds

• Restrict WordPress user registration to prevent attackers from obtaining authenticated access
• Implement IP-based access restrictions for WordPress administrative functions
• Deploy a web application firewall with rules to block command injection attempts
• Remove or deactivate the RomethemeKit For Elementor plugin if not critical to site functionality

# Recommended WordPress security hardening
# Restrict plugin installation to specific administrator IPs
# Add to wp-config.php:
define('DISALLOW_FILE_MODS', true);

# Or implement .htaccess restrictions for wp-admin
# <Files "admin-ajax.php">
#   Order deny,allow
#   Deny from all
#   Allow from YOUR_TRUSTED_IP
# </Files>
