The Lucky Wheel for WooCommerce – Spin a Sale plugin for WordPress suffers from a PHP code injection vulnerability identified as CVE-2025-14509, classified under CWE-94 (Improper Control of Generation of Code). This vulnerability exists in all plugin versions up to and including 1.1.13 due to the unsafe use of the PHP eval() function on user-supplied input from the 'Conditional Tags' setting. Eval() executes the input as PHP code without adequate validation or sanitization, enabling attackers with Administrator-level access to inject and execute arbitrary PHP code on the web server hosting the WordPress site. In WordPress multisite installations, Site Administrators—who typically have limited code editing capabilities—can exploit this flaw to execute arbitrary code, escalating their privileges beyond intended boundaries. The vulnerability requires authenticated access with high privileges but does not require user interaction beyond that. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability, with network attack vector and low attack complexity. Although no known exploits are currently observed in the wild, the vulnerability poses a significant risk due to the potential for full site compromise, data theft, defacement, or pivoting to internal networks. The lack of available patches at the time of disclosure necessitates immediate risk mitigation by administrators. This vulnerability highlights the dangers of using eval() on untrusted input and the importance of strict input validation in WordPress plugins, especially those with administrative configuration interfaces.

For European organizations, the impact of this vulnerability can be severe, especially for e-commerce businesses relying on WooCommerce and the Lucky Wheel plugin for promotional activities. Successful exploitation allows attackers to execute arbitrary PHP code, potentially leading to full server compromise, data breaches involving customer and payment information, defacement of websites, or use of the compromised server as a launchpad for further attacks within the network. In multisite WordPress environments common in larger organizations or managed hosting providers, Site Administrators gaining unauthorized code execution can bypass intended privilege restrictions, increasing the risk of insider threats or lateral movement. The disruption of availability could affect sales and customer trust, while confidentiality breaches could lead to regulatory penalties under GDPR if personal data is exposed. The vulnerability's exploitation could also undermine the integrity of promotional campaigns and customer engagement tools, damaging brand reputation. Given the widespread use of WooCommerce in Europe and the popularity of WordPress multisite setups, the threat is relevant across multiple sectors including retail, hospitality, and digital services.

Immediate mitigation steps include disabling or uninstalling the Lucky Wheel for WooCommerce – Spin a Sale plugin until a secure update is released. Administrators should audit and limit the number of users with Administrator or Site Administrator privileges to reduce the attack surface. Implement strict role-based access controls and monitor administrative actions for suspicious behavior. Employ Web Application Firewalls (WAFs) with custom rules to detect and block attempts to exploit the eval() injection vector, focusing on requests modifying the 'Conditional Tags' setting. Regularly back up WordPress sites and test restoration procedures to minimize downtime in case of compromise. Once a patch is available, apply it promptly and verify that the plugin no longer uses eval() on user input. Consider using security plugins that scan for malicious code injections and monitor file integrity. For multisite environments, review and harden Site Administrator permissions and disable plugin/theme file editing where possible. Educate administrators about the risks of unsafe code practices and the importance of validating plugin inputs.
