Two significant security vulnerabilities have been identified in the Fancy Product Designer premium plugin, which is popular for customizing WooCommerce products. Despite the ongoing usage of the plugin within WordPress websites, these issues remain unaddressed in its latest version, 6.4.3, putting site administrators and their customers at risk. The plugin, developed by Radykal, has notably surpassed 20,000 sales owing to its extensive product customization capabilities. However, Patchstack researchers uncovered two critical vulnerabilities last year: an unauthenticated arbitrary file upload vulnerability (CVE-2024-51919) and an unauthenticated SQL injection vulnerability (CVE-2024-51818).
Examining these vulnerabilities reveals two alarming potential exploits. The unauthenticated arbitrary file upload vulnerability allows users without any authentication to upload various file types, including potentially malicious PHP files. This may lead to remote code execution (RCE), endangering the integrity of the entire website. The problem arises from the functions save_remote_file and fpd_admin_copy_file, which inadequately verify user inputs; this failure allows unwarranted file uploads without proper restrictions.
The second vulnerability, the unauthenticated SQL injection, permits unauthorized users to execute SQL queries directly on a WordPress database. This issue is traced back to the get_products_sql_attrs function, which lacks adequate input sanitization. The current reliance on the strip_tags function is insufficient to mitigate potential SQL injection risks, leaving the database open to manipulation and data breaches.
On March 18, 2024, Patchstack researchers contacted the vendor regarding these vulnerabilities but have not received a satisfactory response. The public disclosure of these vulnerabilities occurred on January 8, 2025, further underlining the urgency for a resolution. Given the nature of these vulnerabilities, site administrators relying on the Fancy Product Designer plugin should act promptly. Deactivating or removing the plugin is advisable until a security patch is confirmed.
A focus on security best practices can help mitigate such risks in the future. Developers should ensure rigorous validation of all file uploads, incorporating checks on both filenames and file extensions. Implementing a whitelist of allowed file types is a proactive measure that can significantly reduce the chances of harmful file uploads. Furthermore, using prepared statements for SQL queries is essential to prevent SQL injection attacks. In parallel, all user inputs should be sanitized and escaped properly. Regular code audits and updates are recommended as part of an ongoing security strategy, particularly for WordPress plugins where vulnerabilities can evolve quickly.
Addressing these issues not only protects individual sites but also builds trust with customers, leading to potential increases in revenue. The immediate costs associated with deactivating or removing a plugin may be overshadowed by the long-term financial and reputational damage that can result from breaches caused by unchecked vulnerabilities. Therefore, a proactive approach in recognizing and rectifying such flaws is crucial for maintaining the integrity and security of software systems.
In sum, the vulnerabilities identified in the Fancy Product Designer plugin underscore the necessity for vigilance within the growing ecosystem of WordPress plugins and themes. By taking definitive actions to patch known vulnerabilities and adopting stringent validation and sanitization practices, developers and site administrators can minimize risk and enhance the overall security posture of their WordPress websites.
