CVE-2025-47640 is a critical SQL Injection vulnerability identified in the Printcart Web to Print Product Designer plugin for WooCommerce, affecting all versions up to 2.3.8. This vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated attacker to inject malicious SQL code through the plugin's input fields or parameters. The vulnerability has a CVSS 3.1 base score of 9.3, indicating a critical severity level. The vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L reveals that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality with a high impact, while integrity is not affected and availability impact is low. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. Exploitation could allow attackers to extract sensitive data from the underlying database, such as customer information, order details, or other business-critical data stored by the WooCommerce platform. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the vulnerability make it a significant threat. The lack of available patches at the time of publication increases the urgency for mitigation. This vulnerability specifically targets the Printcart plugin, which integrates with WooCommerce, a widely used e-commerce platform on WordPress, making it relevant to many online retailers using this combination.

For European organizations, especially e-commerce businesses using WooCommerce with the Printcart Web to Print Product Designer plugin, this vulnerability poses a serious risk. Successful exploitation could lead to unauthorized disclosure of sensitive customer data, including personal and payment information, potentially violating GDPR and other data protection regulations. This could result in legal penalties, reputational damage, and loss of customer trust. Additionally, attackers could leverage extracted data for further attacks such as phishing or fraud. The critical confidentiality impact combined with the broad network attack vector means that organizations with publicly accessible WooCommerce sites are at high risk. The low availability impact suggests that service disruption is less likely, but data breaches remain a primary concern. The vulnerability's presence in a plugin that customizes product design workflows may also affect business continuity if exploited, as attackers might manipulate or exfiltrate design data or order information.

Immediate mitigation steps include disabling or removing the vulnerable Printcart plugin until a security patch is released. Organizations should monitor vendor communications for updates or patches addressing CVE-2025-47640. In the interim, applying Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the plugin's endpoints can reduce exposure. Conduct thorough input validation and sanitization on all user inputs related to the plugin, if customization is possible. Regularly audit and monitor database access logs for suspicious queries indicative of injection attempts. Employ network segmentation to limit database exposure and restrict access to the WooCommerce backend. Additionally, ensure that backups are up-to-date and tested to enable recovery in case of data compromise. Organizations should also review their incident response plans to prepare for potential exploitation scenarios involving e-commerce data breaches.
