CVE-2025-14541 in Lucky Wheel Giveaway Plugin
Summary
by MITRE • 02/11/2026
The Lucky Wheel Giveaway plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0.22 via the conditional_tags parameter. This is due to the plugin using PHP's eval() function on user-controlled input without proper validation or sanitization. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server.

The Lucky Wheel Giveaway plugin for WordPress presents a critical remote code execution vulnerability that affects all versions up to and including 1.0.22. This vulnerability stems from the plugin's improper handling of user-controlled input through the conditional_tags parameter, creating a dangerous attack vector that can be exploited by authenticated attackers with administrator privileges or higher. The flaw represents a severe security weakness that allows malicious actors to execute arbitrary code on the affected WordPress server, potentially leading to complete system compromise and unauthorized access to sensitive data.
The technical implementation of this vulnerability involves the plugin's reliance on PHP's eval() function, which is inherently dangerous when processing untrusted input. The conditional_tags parameter receives user-provided data that flows directly into the eval() function without any form of input validation, sanitization, or escaping mechanisms. This primitive approach to handling user input violates fundamental secure coding practices and creates an environment where attackers can inject malicious PHP code that gets executed with the privileges of the web server. The vulnerability is classified as a CWE-94 (Improper Control of Generation of Code) under the Common Weakness Enumeration framework, specifically representing an unsafe use of dynamic code execution capabilities.
The operational impact of this vulnerability extends far beyond simple code execution, as it provides attackers with complete control over the affected WordPress installation. An authenticated administrator with sufficient privileges can leverage this vulnerability to upload malicious files, modify existing code, establish backdoors, or even escalate their privileges further within the network. The attack surface is particularly concerning because WordPress administrators typically have extensive permissions within the system, making the compromise of such accounts especially damaging. This vulnerability can be exploited to perform actions such as data exfiltration, defacement of websites, deployment of malware, or use of the compromised server as a launchpad for further attacks within the network infrastructure.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary solution involves updating to the latest version of the Lucky Wheel Giveaway plugin where the vulnerability has been patched and the unsafe eval() usage has been eliminated. Administrators should also implement additional security measures such as restricting administrative access to only essential personnel, implementing strong authentication mechanisms including multi-factor authentication, and regularly auditing plugin installations for security vulnerabilities. The ATT&CK framework categorizes this vulnerability under T1059.007 (Command and Scripting Interpreter: PowerShell) and T1566.001 (Phishing: Spearphishing Attachment) as potential attack vectors, emphasizing the need for comprehensive security monitoring and incident response procedures. Organizations should also consider implementing web application firewalls and input validation rules to prevent similar vulnerabilities in other applications.
