CVE-2025-30879 identifies a critical SQL Injection vulnerability in the MC Woocommerce Wishlist plugin developed by Moreconvert Team, specifically in versions up to 1.8.9. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to manipulate backend database queries. SQL Injection is a well-known attack vector where malicious actors can inject arbitrary SQL code through input fields or parameters that are not properly sanitized or parameterized. In this case, the plugin fails to adequately sanitize user-supplied input before incorporating it into SQL statements, leading to the possibility of executing unintended commands on the database. This can result in unauthorized data retrieval, modification, or deletion, potentially compromising sensitive customer and transactional data within WooCommerce stores. The vulnerability was reserved and published in late March 2025, with no CVSS score assigned yet and no known exploits in the wild. Given the plugin’s role in managing user wishlists, attackers might leverage this flaw to access or corrupt user preferences, but the impact could extend to broader database compromise depending on the underlying database permissions and configuration. The lack of an official patch at the time of disclosure increases the urgency for affected organizations to implement interim mitigations. The vulnerability affects a widely used e-commerce plugin, increasing the risk profile for online retailers relying on WooCommerce platforms integrated with this wishlist functionality.

The impact of CVE-2025-30879 is significant for organizations using the MC Woocommerce Wishlist plugin in their WooCommerce e-commerce environments. Successful exploitation can lead to unauthorized access to sensitive customer data, including personal information and shopping preferences, which can result in privacy violations and regulatory non-compliance. Attackers may also modify or delete wishlist data, undermining customer trust and causing operational disruptions. In worst-case scenarios, SQL Injection can be escalated to compromise the entire database backend, potentially exposing payment data or other critical business information. This can lead to financial losses, reputational damage, and legal consequences. The vulnerability’s presence in a popular e-commerce plugin increases the attack surface for cybercriminals targeting online retail platforms globally. Since no authentication or user interaction requirements are specified, the attack could be remotely executed by unauthenticated users, increasing the ease of exploitation. The absence of known exploits currently provides a limited window for remediation before active exploitation emerges.

To mitigate CVE-2025-30879, organizations should prioritize updating the MC Woocommerce Wishlist plugin to a patched version once it becomes available from Moreconvert Team. Until an official patch is released, administrators should implement strict input validation and sanitization on all user inputs related to the wishlist functionality, ensuring that special characters are properly escaped or filtered. Employing parameterized queries or prepared statements in any custom code interacting with the plugin’s database can prevent injection attacks. Additionally, restricting database user permissions to the minimum necessary can limit the potential damage from exploitation. Monitoring web application logs for unusual SQL query patterns or errors can help detect attempted exploitation. Web Application Firewalls (WAFs) configured with SQL Injection detection rules can provide a protective barrier against automated or manual injection attempts. Organizations should also conduct security audits and penetration testing focused on the wishlist feature to identify and remediate any related vulnerabilities. Finally, educating development and operations teams about secure coding practices and the risks of SQL Injection will help prevent similar issues in the future.
